🍨 Fast Gelato Seeds — Sunset Sherbet × Thin Mint GSC, 6–7 Week Flower
Fast Gelato seeds carry the Sunset Sherbet × Thin Mint Girl Scout Cookies genetics of Sherbinski and Cookie Fam's original Gelato — the sweet-cream, citrus, and dessert terpene profile that made Gelato one of the defining strains of the modern West Coast flavour movement — with flowering time cut to 6–7 weeks through a cross with an early-flowering photoperiod line. Gelato was bred in San Francisco by Sherbinski and Cookie Fam, combining the fruity creaminess of Sunset Sherbet with the complexity and potency of Thin Mint Girl Scout Cookies. The result defined what "dessert cannabis" meant for a generation of growers and consumers — a limonene-forward sweet-cream and citrus profile layered over an earthy cookie base, at 22–26% THC with a balanced euphoric-then-settled effect.
What the Fast Version changes — and what it doesn't: The Fast Version genetics are produced by crossing stable Gelato photoperiod genetics with an early-flowering photoperiod line — not Ruderalis, not autoflower. The plant still requires a 12/12 light flip to trigger flower. What changes is the flowering window: 6–7 weeks instead of the 8–10 weeks of standard Gelato. The terpene profile, THC potency, and yield potential of the original are preserved. For growers who want the genuine Gelato genetics without the extended flower period — or who need to finish earlier in the outdoor season — the Fast Version delivers both without compromise.
What Fast Gelato seeds do well:
- Full Gelato terpene expression in a shorter window: Sweet cream, citrus zest, blueberry, and earthy cookie base — the dessert profile the strain is known for. Evolves from citrus-sherbety in early flower to a richer, fuel-driven cream by week 6
- Exceptional resin production: The Sherbet × GSC lineage produces heavy trichome coverage from week 3 of flower — one of the stronger candidates for solventless rosin and dry-sift in the catalogue
- Earlier outdoor finish: Harvesting in early-to-mid March in northern Australia and late March–early April further south — meaningfully earlier than standard Gelato, and out of the late-autumn humidity window that affects later-finishing genetics
- Colour development under cool conditions: The Sunset Sherbet heritage produces lavender and magenta hues when night temperatures drop below 20°C in late flower — visually striking and consistent with the Sherbet lineage
- SCROG and canopy training: Compact, bushy structure with dense lateral branching that fills a SCROG screen efficiently. Strong node spacing and uniformity make canopy management predictable

🍨 What We Love About Fast Gelato Seeds
The resin production is the most immediate standout. The Sherbet × GSC trichome density is visible from week 3 of flower — earlier than most photoperiod genetics — and builds to a genuinely impressive coverage by week 6. For growers interested in solventless extraction alongside flower, Fast Gelato seeds are one of the stronger options in the catalogue. The limonene-dominant terpene profile carries through into rosin with exceptional flavour retention.
The aroma evolution through the flower period is worth growing this strain for on its own. It starts sweet and sherbety in early flower — soft citrus cream. By week 5–6 it deepens into a richer, more complex fuel-driven cream that's louder and more characteristically Gelato. Both phases are pleasant; the late-flower expression is the one the strain is famous for. Carbon filtration is non-negotiable from week 4 onward.
The shortened flower window is practically significant for Australian outdoor growers. Early-to-mid March harvests in northern Australia avoid the late-summer humidity spikes that affect strains finishing in April. For indoor growers running consecutive cycles, 6–7 weeks of flower compared to 8–10 weeks produces meaningfully more runs per year from the same space.
🌿 Fast Gelato Effects & Experience
Onset (10–20 minutes): Uplifting and warm. The Gelato genetics produce a clear, euphoric lift — mood elevates, creative energy increases, social engagement comes naturally. Not a sharp or racy onset. The limonene component contributes citrus brightness. Functional and pleasant from the beginning.
Early phase (20–60 minutes): Euphoric and social at its most active. Creative focus, easy conversation, comfortable engagement with music or art. The Thin Mint GSC indica genetics contribute a steady physical warmth underneath the mental lift — grounding without competing with the sativa clarity. The sweet-cream flavour most present in this window.
Mid-phase (60–120 minutes): The balanced 55/45 indica-sativa genetics produce a gentle settling. Physical ease deepening progressively while mental brightness remains. Comfortable, present, and settled rather than active. Appetite reliably increases at this point — the GSC and Sherbet lineage both contribute.
Late-phase (2+ hours): Calm, comfortable body ease as the primary sensation. The myrcene and humulene components contribute to a grounding, earthy quality at the end of the session. Sleep is a natural outcome for many users; at moderate doses a comfortable, contented wind-down.
Duration: 3–4 hours at typical doses. Consistent with the balanced hybrid genetics and the 22–26% THC range.
Potency consideration: At 22–26% THC with Gelato genetics that carry the same depth of effect as the Cookies Fam lineage, Fast Gelato seeds are meaningfully potent. The euphoric onset is smooth and warm but the potency is genuine. Start at one to two hits and allow 20 minutes before assessing.
Flavour profile: Sweet cream and citrus on the inhale — the limonene-forward sherbety quality of the Sunset Sherbet parentage. Blueberry and earthy cookie depth in the middle. The exhale carries a richer, more complex cream and subtle fuel note that develops fully in late flower. With a proper 3–4 week cure the full dessert complexity sharpens — assess the genetics at 4 weeks in the jar, not at 1 week post-harvest.
🌱 Growing Fast Gelato Seeds — Complete Guide
(The following is provided for ACT licence holders and growers in legal jurisdictions overseas.)
Experience level required: Intermediate. Fast Gelato seeds are stable and resilient by Cookies Fam genetics standards — more consistent and forgiving than many modern exotic genetics. The main challenges are managing the 50–70% flowering stretch, maintaining airflow through the dense late-flower bud structure, and understanding that trichomes appear as early as week 3 but the buds don't reach full size and density until week 6–7. Growers who've run a Cookies-derived or Gelato photoperiod before will find the Fast Version predictable and rewarding. The critical adjustment from standard Gelato is the shortened flower window — most other management decisions are the same.
Important — what "Fast Version" means: Fast Gelato seeds still require a 12/12 light flip to trigger flowering. They are not autoflowers and will not flower under an 18/6 light schedule. The "fast" refers to the shortened bloom period (6–7 weeks instead of 8–10), achieved by introducing an early-flowering photoperiod line into the genetics. Veg and flip management is identical to any other photoperiod — only the flower duration is compressed.
Veg phase: Grow under 18/6 until the plant is the size you want to flower. 4–6 weeks of veg produces a medium plant suited to most indoor setups. The compact, bushy Gelato structure responds well to topping from week 3–4 and LST from early in veg. The 50–70% stretch after the flip means you should flip at a plant height that leaves room for this increase — a 60 cm plant at flip will reach 90–102 cm at full height in a standard scenario.
Height and stretch: Expect 50–70% height increase in the first 2–3 weeks of flower from the Sunset Sherbet sativa contribution. Plan tent height and light distance proactively — adjust light distance every 2–3 days through the stretch rather than every week.
Training:
SCROG: The standout technique for Fast Gelato seeds. The compact, bushy structure with dense lateral branching fills a screen efficiently. Set at 40–50 cm, weave through as the plant grows in veg, flip when 60–70% full.
Topping: Recommended from week 3–4 of veg. The Gelato genetics recover well from topping. Top at node 4–5 for a multi-cola structure.
LST: Effective alongside topping or standalone for canopy management and stretch control.
Harvest timing — the critical note with Fast Gelato seeds: Trichomes appear as early as week 3 of flower, producing a convincing frost that can create a false sense of harvest readiness. The buds continue to pack on size and density right through to week 6–7. Harvesting early at the first sign of full trichome coverage consistently costs 20–30% of final yield and misses the peak dessert flavour development. Check trichomes from week 5 of flower. Harvest at 15–20% amber for the balanced Gelato effect.
Colour development: Fast Gelato seeds develop lavender and magenta hues when night temperatures drop below 20°C in late flower — a visual characteristic of the Sunset Sherbet parentage. Drop nights to 17–19°C from week 4 of flower to encourage the colour expression. The colour is cosmetic and doesn't affect potency or flavour.
Airflow and humidity: The dense, dessert-lineage buds produce significant trichome coverage and tight internodes that can trap humidity in still air from week 4 of flower. Keep RH below 50% from flower week 4, below 45% from week 5, and maintain oscillating fans covering the inner canopy throughout late flower. This is more demanding than standard-density photoperiod genetics.
Extraction potential: Fast Gelato seeds are among the stronger candidates for solventless rosin and dry-sift in the catalogue. The terpene density, early trichome development, and Sherbet × GSC lineage produce high yield and exceptional flavour carryover post-press.
🏠 Indoor Growing (Australia)
- Veg time: 4–6 weeks under 18/6 — account for 50–70% stretch when determining flip height
- Flower time: 6–7 weeks from 12/12 flip — meaningfully shorter than standard Gelato
- Yield: 500–600 g/m² with SCROG, topping, and consistent environment
- Container: 15–20 L
- Light schedule: 18/6 veg, 12/12 to trigger flower — this is a photoperiod, not an auto
- Height: 100–150 cm at full height — plan tent clearance for the 50–70% flowering stretch
- Training: SCROG or topping plus LST strongly recommended for canopy management and yield
- Airflow: Critical from flower week 4. Dense Cookies-lineage bud structure — RH below 50% from week 4, below 45% from week 5. Oscillating fans covering inner canopy throughout
- Aroma: Sherbety citrus-cream from flower week 2–3, intensifying to fuel-driven cream by week 5–6. Carbon filtration essential from flower week 3
- Harvest timing: Check from flower week 5. Don't harvest at first full frost (week 3–4) — buds swell significantly through week 6–7. Target 15–20% amber
- Colour: Drop nights below 20°C from flower week 4 for lavender/magenta hue development
🌿 Outdoor Growing (Southern Hemisphere / Australia)
- Planting: October–November for a full Australian summer veg
- Harvest windows:
- Queensland / Northern NSW: Early–mid March
- Central NSW / Victoria / SA: Mid–late March
- Southern states: Early April
- The outdoor timing advantage: March harvests avoid the late-summer and early-autumn humidity conditions that affect April–May finishers. For coastal Australian growers in humid regions, this is a meaningful practical benefit
- Yield: 650–800 g per plant with a full summer veg, 20–30 L containers, and full sun. Upper end requires the full outdoor setup
- Height: 120–180 cm with a full season — stake from week 3 of flower
- Site: Full sun, 6+ hours direct light. Natural airflow around the plant an advantage for the dense bud structure
- Colour outdoors: Australian late-summer and early-autumn nights naturally provide the cool temperatures that trigger the Sherbet-lineage colour expression. March finishes often produce excellent natural colour development
🧪 Fast Gelato Seeds EC & Feeding Guide — Soil and Coco
Fast Gelato seeds are moderate feeders with a specific calcium demand that's higher than most genetics in the catalogue — the Sherbet × GSC lineage is CalMag-hungry throughout the grow, particularly in coco. The 6–7 week flower window means the peak feeding period is compressed — EC transitions need to be executed on time rather than stretched over the extended flower windows of standard photoperiods. The limonene-dominant dessert terpene profile also benefits from conservative nitrogen in late flower. Back off nitrogen from flower week 3 to protect the sweet-cream character through weeks 5–6.
All EC values assume quality base nutrients. Australian tap water typically runs 0.2–0.5 EC — factor this into your target. Measure after mixing.
📊 EC & pH Target Table — Soil vs Coco
| Phase | Soil EC | Coco EC | Soil pH | Coco pH | Notes |
|---|---|---|---|---|---|
| Seedling Weeks 1–2 |
0.4–0.6 | 0.5–0.8 | 6.2–6.5 | 5.8–6.0 | Plain water in week 1. Begin CalMag supplementation in coco from week 1 — the Sherbet × GSC lineage is calcium-hungry from the start. |
| Early veg Weeks 3–5 |
0.8–1.2 | 1.0–1.4 | 6.0–6.5 | 5.8–6.2 | Nitrogen-forward. Build on plant response. CalMag 1–2 ml/L throughout. Watch tips — Gelato genetics show Cookies-lineage sensitivity. |
| Late veg Weeks 5–8 |
1.2–1.6 | 1.4–1.8 | 6.0–6.5 | 5.8–6.2 | Maintain nitrogen. SCROG filling or LST in progress. Flip when at desired height — account for 50–70% stretch post-flip. CalMag ongoing. |
| Early flower Flower weeks 1–3 |
1.2–1.6 | 1.4–1.8 | 6.0–6.5 | 5.8–6.2 | Stretch occurring — adjust light distance regularly. Begin transitioning to bloom nutrients. K support from flower week 2. Trichomes appear from week 3 — don't harvest, buds haven't yet swelled. |
| Peak flower Flower weeks 3–6 |
1.4–1.8 | 1.6–2.0 | 6.0–6.5 | 5.8–6.2 | High P and K. Back off nitrogen from flower week 3 — the dessert terpene profile suffers with excess N in the compressed 6–7 week window. Airflow critical from flower week 4. RH below 50%. |
| Late flower Flower weeks 5–7 |
1.0–1.4 | 1.2–1.6 | 6.0–6.5 | 5.8–6.2 | Taper EC down. Check trichomes from flower week 5. Buds still swelling significantly — don't harvest at first amber. Target 15–20% amber for balanced Gelato effect. |
| Flush Final 7–10 days |
0.0–0.4 | 0.0–0.5 | 6.2 | 5.8–6.0 | Flush until runoff EC drops below 0.5. The cream-citrus-dessert terpene profile is noticeably cleaner after a proper flush. Don't shorten — compressed flower window means the plant has had more EC per day than a standard photoperiod. |
💡 Feeding Key Principles — Fast Gelato Seeds
- CalMag throughout, no exceptions: The Sherbet × GSC lineage is specifically calcium-hungry. 1–2 ml/L CalMag from seedling to flush in coco; consistent CalMag in soil. Brown spots on mid-canopy leaves with correct pH almost always indicate calcium deficiency with these genetics
- Avoid aggressive EC ramping: Gentle, consistent EC increases rather than hard jumps. The Gelato genetics perform better with steady moderate feeding than with spikes and corrections
- Back off nitrogen from flower week 3: Earlier than most photoperiods given the compressed 6–7 week window. The sweet-cream dessert terpene character suffers with excess nitrogen — back off N promptly at the flip
- Don't shorten the flush because the flower is short: A proper 7–10 day flush is just as important — possibly more so given the plant has processed more EC per day in the compressed flower window
- Cure completes the dessert profile: 3–4 weeks in sealed jars at 60–65% RH. The full citrus-cream-cookie complexity develops during cure — assess at 4 weeks, not 1 week post-harvest
🗓️ Fast Gelato Seeds — Grow Timeline Overview
Fast Gelato seeds run 6–7 weeks of flower — the compressed timeline requires more decisive EC transitions and earlier airflow management than standard photoperiods. The stretch is significant (50–70%) and the harvest timing requires patience despite the early trichome coverage from week 3.
| Phase | What's Happening | Key Actions | Watch Out For |
|---|---|---|---|
| Veg Weeks 1–6+ |
Compact bushy vegetative growth with dense lateral branching. Responsive to topping and LST. SCROG filling well given the tight internodes. | Top at node 4–5. Begin SCROG or LST. 18/6. EC 0.8–1.6 (soil) — build gradually. CalMag from week 1 in coco. Flip when 60–70% screen full. | Flip height — the 50–70% stretch post-flip means flipping at the right height is more critical than with low-stretch genetics. Plan the tent headroom before flipping. |
| Early flower Flower weeks 1–3 |
Significant stretch — 50–70% height increase. Bud sites establishing across the SCROG. Sweet-sherbety citrus aroma building from week 2. Trichomes appearing from week 3. | Adjust light distance every 2–3 days for stretch. Transition to bloom nutrients. EC 1.2–1.6. Begin K support from flower week 2. Back off N from flower week 3. | The week 3 frost — trichomes appearing this early creates false readiness. The buds are just beginning to develop. Don't harvest here. Check trichomes from flower week 5. |
| Peak flower Flower weeks 3–6 |
Dense Gelato bud development. Aroma deepening from sherbety-citrus to rich fuel-cream by week 5–6. Resin coverage heavy. Colour developing under cool nights. Buds still swelling. | Peak EC 1.4–1.8. RH below 50% from flower week 4. Active inner canopy airflow. Carbon filter essential. Cool nights (below 20°C) for colour. Check trichomes from flower week 5. | Airflow complacency — the Sherbet × GSC density in the inner canopy from flower week 4 requires active management. Don't ease off environmental control as the harvest approaches. |
| Late flower / harvest Flower weeks 5–7 |
Buds reaching full size and density. Full fuel-cream dessert aroma at peak. Trichomes at 15–20% amber. The genuine harvest window. | Flush from flower week 5 when 10–15% amber visible. Harvest at 15–20% amber. Slow dry at 15–18°C, 55–60% RH for 10–14 days. | Rushing the dry — limonene and caryophyllene dessert terpenes are volatile. Slow and cool to preserve the cream-citrus-cookie profile. |
| Cure | The full cream-citrus-cookie dessert complexity develops in the jar. At 4 weeks it tastes like Gelato is supposed to taste. | Jar at 60–65% RH. Burp daily 2 weeks. Seal and wait. 3 weeks minimum. 4 weeks for full dessert depth. | Assessing at 1 week — the Gelato terpene profile develops significantly during cure. Assess at 4 weeks. |
🔍 Fast Gelato Seeds — Common Myths vs Reality
| The Myth | The Reality |
|---|---|
| "The Fast Version is an autoflower." | Fast Gelato seeds are a photoperiod — they still require a 12/12 light flip to trigger flowering. The "fast" comes from crossing with an early-flowering photoperiod line, not Ruderalis. Running it under 18/6 indefinitely will keep it in veg. It is not an autoflower and should not be managed as one. |
| "Trichomes appearing at week 3 means it's nearly ready." | Fast Gelato seeds produce visible trichome coverage from week 3 of flower — significantly earlier than most genetics. This is not a harvest signal; it's a characteristic of the Sherbet × GSC lineage. The buds continue to pack on significant size and density right through week 6–7. Harvesting at week 3–4 frost consistently costs 20–30% of final yield and misses the peak dessert flavour. Check trichomes from flower week 5 and harvest at 15–20% amber. |
| "6–7 week flower means a shorter flush." | The flush duration should remain 7–10 days regardless of the compressed flower window. In fact, the concentrated feeding in a shorter period means the plant may have processed more EC per day than a standard photoperiod — a thorough flush is equally or more important. Don't shorten the flush to gain a few days on the timeline. |
| "The Fast Version produces lower quality than standard Gelato." | The Fast Version genetics preserve the Sunset Sherbet × Thin Mint GSC terpene profile, THC potency, and resin quality of the original. The compression of the flower period doesn't compromise the genetics — it's achieved through early-flowering photoperiod line crossing rather than any dilution of the Gelato lineage. Growers who respect the harvest timing (don't cut early despite the week 3 frost) and complete a proper flush and cure produce material indistinguishable from standard Gelato quality. |
| "Dense Cookies-lineage buds manage humidity on their own." | The Sherbet × GSC bud density actively traps humidity in the inner canopy from flower week 4. Without active airflow management — oscillating fans covering the inner canopy, RH below 50% from flower week 4 — late-flower mould is a genuine risk with Fast Gelato seeds in the same way it is with any dense Cookies-derived genetics. The compressed flower window doesn't reduce this risk; it concentrates it into a shorter period. |
🧠 Jason's Tip — Growing Fast Gelato Seeds
The week 3 frost is the thing that catches growers out with this strain every time. Fast Gelato seeds develop visible trichome coverage earlier than almost anything else in the catalogue — by flower week 3 the buds look convincingly ready, especially if you're used to genetics that don't trich up until week 6. Don't harvest. The buds are still small at week 3. They will double in size and density between week 3 and week 6. I check trichomes from week 5 and harvest at 15–20% amber. Waiting those extra weeks is where the dessert flavour and the yield are.
The CalMag is the other thing to stay on top of. The Sherbet × GSC lineage is specifically calcium-hungry — more so than most other genetics I've grown. If you're in coco, start CalMag from week 1 and don't stop until the flush. Brown spots on mid-canopy leaves are almost always calcium deficiency with these genetics, especially in coco. Check pH first, then CalMag — don't reduce EC in response before you've ruled those two out.
On the stretch — this plant puts on 50–70% after the flip, which is more than the compact bushy structure in veg suggests it will. I flip Fast Gelato seeds at a height that gives them plenty of room to grow into. Adjusting light distance every 2–3 days through the stretch rather than every week keeps the canopy at the right distance without scrambling at the end.
🍨 Is Fast Gelato Right for Your Grow?
✅ Fast Gelato seeds are the right choice if:
- You want the Sunset Sherbet × Thin Mint GSC cream-citrus-dessert terpene profile at 22–26% THC with a 6–7 week flower window
- Finishing 2–3 weeks earlier than standard Gelato matters — indoor cycle frequency or outdoor timing
- Australian outdoor harvest in March rather than April suits your season better — avoiding late-summer humidity or finishing before the autumn change
- Solventless extraction is a goal alongside flower — the Sherbet × GSC resin density and terpene profile are exceptional for rosin
- SCROG with a compact, bushy, well-branched plant is your preferred indoor approach
- You can manage the CalMag demand, the 50–70% flowering stretch, and active late-flower airflow
❌ Consider alternatives if:
- You want a fixed auto timeline — Fast Gelato seeds are a photoperiod and require a 12/12 flip. There is no autoflower version currently in the catalogue
- You want to avoid the Cookies-lineage CalMag demand and feeding sensitivity — robust hybrid genetics like Gorilla Glue or Trainwreck-derived strains are more forgiving
- Tent height is a constraint at or below 150 cm — the 50–70% flowering stretch pushes Final height to 100–150 cm and requires adequate headroom
- You want to harvest earlier than March outdoors in northern Australia — the shorter flower window still requires natural day length to trigger
🍨 Real User Experiences
⭐⭐⭐⭐⭐ "Gelato is always my crowd-pleaser. The Fast Version keeps the creamy terps but finishes two weeks sooner. Unreal resin production for the flower time — and the aroma at week 6 is exactly what Gelato should smell like." — Indoor grower, Australia
⭐⭐⭐⭐ "Compact plant, strong aroma. Needed extra airflow from week 4 of flower — the dense buds were holding humidity in the inner canopy. Sorted that out and the end result was top-quality Gelato genetics. Worth the attention to detail." — Indoor grower, Australia
❓ Frequently Asked Questions — Fast Gelato Seeds
🍨 What are Fast Gelato seeds?
Fast Gelato seeds are a feminised photoperiod cannabis strain bred from Sunset Sherbet × Thin Mint Girl Scout Cookies — the Cookie Fam / Sherbinski genetics that produced one of the most flavour-defining strains of the modern West Coast cannabis movement — with an early-flowering photoperiod line crossed in to reduce bloom time to 6–7 weeks. The plant still requires a 12/12 light flip to flower; it is not an autoflower. The shorter flower window preserves the full Gelato terpene profile, potency, and yield potential while finishing 2–3 weeks earlier than standard Gelato.
🍦 Does Fast Gelato keep the original Gelato flavour?
Yes — the Sunset Sherbet × Thin Mint GSC terpene profile is fully preserved. Sweet cream, citrus zest, blueberry, and earthy cookie base in early flower, evolving to a richer fuel-driven cream by week 5–6. The full dessert complexity develops in the jar over 3–4 weeks of cure — fresh-dried material gives a decent impression but assess the genetics at 4 weeks in the jar, not at 1 week post-harvest.
⏱ How long does Fast Gelato take from seed to harvest?
4–6 weeks of veg plus 6–7 weeks of flower — typically 10–13 weeks total from seed depending on veg length. The 6–7 week flower window is the defining characteristic: 2–3 weeks shorter than standard Gelato's 8–10 week flower. Check trichomes from flower week 5. Don't harvest at the first full frost (week 3–4) — the buds continue to swell significantly through week 6–7. Harvest at 15–20% amber for the balanced Gelato effect.
📏 How tall does Fast Gelato get and how do I manage the stretch?
100–150 cm at full height — a 50–70% stretch after the 12/12 flip is expected from the Sunset Sherbet sativa genetics. Flip the plant at a height that leaves room for this increase. Adjust light distance every 2–3 days through the stretch rather than weekly. Topping in veg plus LST or SCROG are the most effective techniques for managing the canopy through the stretch window.
🧪 Is Fast Gelato good for extractions?
Yes — one of the stronger candidates in the catalogue for solventless rosin and dry-sift. The Sherbet × GSC trichome density appears from flower week 3 and builds to exceptional coverage by week 6. The limonene-dominant dessert terpene profile carries through into extracts with high flavour retention. Expect above-average rosin yield and notable terpene quality post-press.
💧 Why does Fast Gelato need extra CalMag?
The Sunset Sherbet × Thin Mint GSC lineage has a specific calcium demand that's higher than most genetics in the catalogue. In coco this is most acute — CalMag from week 1 through flush at 1–2 ml/L is the correct approach. In soil, consistent CalMag supplementation through veg and flower. Brown spots on mid-canopy leaves with correct pH almost always indicate calcium deficiency with these genetics rather than overfeeding. Check pH first, then consider CalMag before reducing EC.
