🌸 End of Flowering Week 7 (D43–D49) → Entering Week 8 (D50) | Project WF
We’ve officially closed Flowering Week 7 (Day 43 to Day 49) and are now entering Week 8 (Day 50) — the final and most critical stage where real quality and cleanliness are defined.
This week was focused on root zone correction, EC reduction and preparing the plants for a clean and controlled finish, without forcing maturity or stressing the crop.
🌡️ Environmental Parameters (Week 7 avg)
• Day temperature: 22–23.5 °C
• Night temperature: 18–19 °C
• Relative Humidity: 48–52 %
• VPD: 1.30–1.45 kPa
• PPFD: ~830–850 µmol/m²/s
• CO₂: Ambient (~550–630 ppm)
Stable conditions all week to keep metabolism active while avoiding unnecessary stress during late flowering.
💧 Irrigation & Feeding – Week 7 (Detailed)
📅 25/01 – Day 46
Total volume: 30 L (hand watered, stopping when plants drained)
Recipe:
• Sensi Cal-Mag Xtra → 15 ml
• Bio·Grow → 3 ml
• Bio·Bloom → 120 ml
• Top·Max → 24 ml
• Bio·Heaven → 24 ml
• Bud Candy → 36 ml
• Atazyme → 30 ml
Input values:
• EC: ~0.98 mS
• pH: 6.2
This irrigation initiated nutrient reduction and confirmed uneven salt accumulation between pots.
📅 29/01 – Day 49
Total volume: 50 L (high-volume strategic irrigation)
Recipe:
• Bio·Bloom → 200 ml (4 ml/L)
• Top·Max → 50 ml (1 ml/L)
• Bio·Heaven → 50 ml (1 ml/L)
• Bud Candy → 50 ml (1 ml/L)
• Sensi Cal-Mag Xtra → 15 ml (0.3 ml/L)
• Atazyme → 40 ml (0.8 ml/L)
Input values:
• EC: ~0.78 mS
• pH: 6.2
Drain EC readings (by pot):
• Range: 2.1 – 5.6 mS
• Confirmed salt accumulation now actively being released.
This irrigation was a pre-cleaning step, not a final flush, keeping roots active while opening the substrate.
📊 Week 7 Irrigation Summary
• Total water applied: ~80 L
• Average: ~11.4 L / 24h (including strategic high-volume irrigation)
🌿 Plant Status – End of Week 7
• Controlled senescence has started naturally.
• Strong anthocyanin expression (genetics + environment).
• Buds still finishing density, not rushed.
• Trichomes shifting from clear → cloudy, amber still minimal.
• No signs of acute stress, lockout or stalled metabolism.
🎯 Week 8 Objectives (From Day 50)
Week 8 is about precision, not force.
• Final nutrient closure initiated.
• Progressive root zone cleaning strategy:
• Pre-flush irrigation
• Single controlled Final Flush
• Water-only irrigation
• Dry-back before harvest
• Maintain stable PPFD and VPD to preserve terpenes and resin quality.
• Focus shifts from yield to clean finish, flavor and combustion quality.
This is the phase where premium crops are truly defined.

Open to collaborations and data-driven partnerships with brands focused on precision growing and premium results.
