šø White Widow ā Week 4 of Flower (12/12ā11/13 From Seed)
Stage: Week 4 Flower (full flower, no stretch left)
Structure: Compact plant, building a tall main cola (~25 cm target) + tidy āgolf-ballā 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 ā second flower push ā 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.

š½ļø Nutrition (this week)
Weāve removed Top Booster completely. Current, steady recipe:
⢠Aptus Regulator ā supports cell strength, transport efficiency, and stress tolerance
⢠Aptus CalMag Boost ā LED + coco/active soil insurance for Ca/Mg/Fe availability
⢠Plagron Power Buds ā encourages compact flower set at each node
⢠Plagron Sugar Royal ā metabolic push (N-based aminos) to drive energy use + aroma precursors
⢠Plagron Green Sensation ā balanced late-flower support (PK + organics/biostims) for density, oil, and finish
⢠Aptus All-in-One Liquid ā (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 āearly swellā window: calyx initiation shifts into mass formation. Weāre 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 soilās biology fully ramps, then it can step back.

š¬ Plant Development (whatās 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 6ā7.
⢠Carb sink strength. Flowers become the primary sink; steady water + balanced EC will keep turgor and bulking clean.

š” 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 (11ā12 h), aim ~700ā800 µmolĀ·mā»Ā²Ā·sā»Ā¹ to land a DLI ~28ā32 molĀ·mā»Ā²Ā·dayā»Ā¹āa sweet spot for mid-flower without forcing heat stress.
āø»
š”ļø Environment (steady and sensible)
⢠Temps/RH: Now stable since AC: ~28 °C and mid-60s %RH previously reportedāgreat for mid-flower resin and growth when airflow is strong.
⢠VPD: Around 1.3ā1.4 kPa is ideal for Week 4 bulkākeeps stomata active, minimizes mold risk, and preserves turgor.
⢠COā: Natural room swings are fine at this stage; plant responses are telling us sheās happy.
āø»
š What to Expect Next (Week 5ā6)
⢠Calyx stacking & mass gain on the main cola and those side āgolf balls.ā
⢠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
⢠Heightāsheās done stretching.
⢠True ripening signals (amber heads, heavy fade) ā too early.
⢠Big defoliation needs, sheās compact; keep leaves that drive sugars unless a leaf blocks airflow or a bud site entirely.
āø»
Growerās 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 swingsāperfect for a compact, single-plant showcase.
