🌸 White Widow — Week 4 of Flower (12/12–11/13 From Seed)
Stage: Week 4 Flower (full flower, no stretch left)
Structure: Compact plant, building a tall main cola (~25 cm target) + tidy “golf-ball” side colas
Frost: Already impressive; trichomes thickening across tops and sugar leaves
Watering: Hand watering (by feel; no runoff chasing)
Light routine: Still running the red-on/red-off sunrise/sunset via TrolMaster (15 min before/after)
⸻
Quick Recap (for anyone just joining)
• Germination: We lost the first batch (uneven heat mat, my mistake). We restarted and this solo survivor is the one you see now.
• Veg under 11/13: She stayed compact and stubbornly vegged a while before showing preflower, great node stacking.
• Early flower: Bud set → second flower push → now deep into Week 4 with clear, even sites top to bottom.
• Environment: Room was hot early on; AC install stabilized temps and RH. Plants never showed stress, credit to genetics, steady care, and balanced feed.

🍽️ Nutrition (this week)
We’ve removed Top Booster completely. Current, steady recipe:
• Aptus Regulator – supports cell strength, transport efficiency, and stress tolerance
• Aptus CalMag Boost – LED + coco/active soil insurance for Ca/Mg/Fe availability
• Plagron Power Buds – encourages compact flower set at each node
• Plagron Sugar Royal – metabolic push (N-based aminos) to drive energy use + aroma precursors
• Plagron Green Sensation – balanced late-flower support (PK + organics/biostims) for density, oil, and finish
• Aptus All-in-One Liquid – (still in) gentle full-spectrum base; likely to taper/stop soon as the soil biology carries more of the load
Why this mix now?
Week 4 is the “early swell” window: calyx initiation shifts into mass formation. We’re keeping Ca/Mg steady for membrane integrity and photosynthesis under strong LED; using Power Buds to keep sites tight, Sugar Royal to feed metabolism and terpenes, Green Sensation to support density/oils, and Regulator to keep the plant efficient under heat/PPFD. All-in-One remains as a safety net while the super soil’s biology fully ramps, then it can step back.
⸻
🔬 Plant Development (what’s happening physiologically)
• Stretch is done. Auxin dominance recedes; energy diverts to calyx swelling and trichome biosynthesis.
• Trichomes rising. Expect a marked increase in capitate-stalked heads on bracts and sugar leaves from now through Week 6–7.
• Carb sink strength. Flowers become the primary sink; steady water + balanced EC will keep turgor and bulking clean.
⸻
💡 Light & Rhythm
• Sunrise/sunset with reds (TrolMaster): 15 min before and after the white/blue block to smooth transitions and lean into the red/far-red synergy.
• Target PPFD/DLI: With shorter photoperiods (11–12 h), aim ~700–800 µmol·m⁻²·s⁻¹ to land a DLI ~28–32 mol·m⁻²·day⁻¹—a sweet spot for mid-flower without forcing heat stress.
⸻
🌡️ Environment (steady and sensible)
• Temps/RH: Now stable since AC: ~28 °C and mid-60s %RH previously reported—great for mid-flower resin and growth when airflow is strong.
• VPD: Around 1.3–1.4 kPa is ideal for Week 4 bulk—keeps stomata active, minimizes mold risk, and preserves turgor.
• CO₂: Natural room swings are fine at this stage; plant responses are telling us she’s happy.
⸻
👀 What to Expect Next (Week 5–6)
• Calyx stacking & mass gain on the main cola and those side “golf balls.”
• Frost explosion: More trichomes and a greasy feel on sugar leaves.
• Aroma lift: Expect that classic White Widow earthy-spice to start pushing out.
What not to expect
• Height—she’s done stretching.
• True ripening signals (amber heads, heavy fade) — too early.
• Big defoliation needs, she’s compact; keep leaves that drive sugars unless a leaf blocks airflow or a bud site entirely.
⸻
Grower’s Tips (why the choices matter)
• No Top Booster now: Keeps K spikes in check; prevents Ca/K antagonism and tip burn while the plant is setting long-term resin factories.
• Keep Ca/Mg consistent: Under strong LEDs, Ca deficits appear suddenly in fast-bulking weeks. Stay ahead, not behind.
• Watering style: Hand watering gives you feel-level control over moisture fronts and prevents swings—perfect for a compact, single-plant showcase.
