Visual Development – Day 8 to Day 14
- Plants are clearly transitioning from stretch to flowering
- Longer internodes at the beginning of the week, more compact tips by the end
- Defoliation has ensured good airflow – free stems, no stagnation zones visible
- Even stretch and light distribution through SCROG/net training
- Leaf health very good – lush green and shiny
- Overall appearance: stable, well-trained, very homogeneous
–––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––
Outlook for Flowering Week 3
- IR light remains fully active, continues to support sleep/wake process

⚠️ Root Wizard has been discontinued – recommended only until Flowering Week 2 according to Emerald Harvest schedule.
⸻
Watering Behavior & EC Values
• Watering Amount: currently 3.0 L per plant per day
→ 2.0 L was not enough – plants show significantly more stable behavior with 3.0 L
• EC of Water: 2.0
• Drain EC: 4.0
→ Despite the high value, no symptoms of over-fertilization or stress
→ Coco + PowerZym + daily drain buffer well
⸻

• Effect: Stretch visible but controlled – no over-stretching
⸻
Purolyt Application (starting Week 3)
• Start: Monday of this week
• Application: fine leaf application outside of light phases
• Reason: High external humidity (around 72%), tent humidity remains at ~62% despite dehumidifier
• Goal: microbial hygiene, mold prevention, and climatic stabilization
• No conflict with PowerZym – different action sites (root vs. leaf)
⸻
Plant Condition & Development
• Color: deep green with natural shine
• Growth Form: upright, robust, no signs of deficiency or stress
• Stretch: visible but controlled – IR shows desired effect
• Structure: SCROG-friendly, good light distribution on bud sites
• Lower Third: well defoliated – no waterlogging, good air circulation
• Root Zone: healthy, drain water clear – PowerZym is effective
• Smell: noticeably increasing, first resin formation visible
⸻
Outlook for Flowering Week 4
• Watering amount may be adjusted to 3.2–3.5 L (depending on development)
• UVB remains deactivated (planned start: from Week 6)
• King Kola & Honey Chome will continue
• Purolyt every 2 days for prime effect
• Focus: bud structure, climate resistance, resin formation

Base Nutrients:
– Cali Pro Bloom A: 1.75 ml/L
– Cali Pro Bloom B: 1.75 ml/L
– CalMag Agent (Canna): 0.5 ml/L
Additives:
– Emerald Goddess: 2.0 ml/L

– On defoliation day: only 1.5–2.0 L to reduce stress
– Drain EC: ~4.0 / pH Watering: 5.8 / pH Drain: 6.1
– Plants continue to show healthy uptake and vitality
⸻
🌞 Light Management – IR & UV
IR Light (Spider Farmer IR Bar):
– Morning: 5:30 – 6:30 AM
– Evening: 4:30 – 6:30 PM
– Simulation of sunrise/sunset (Phytochrome adjustment)
– Promotes waking and sleeping rhythm → better energy utilization and calming
– In Week 1: 13 h of continuous IR light for targeted stretch promotion
UV Light:
– Start planned from Day 30 (end of Week 4)
– Begins with 20 min/day (e.g., 8:00 – 8:20 PM)
– Goal: Stimulation of trichome production without stress
– Distance to plant: at least 60 cm
– Increase to max. 2 h by Week 6
⸻
đź’§ Climate & Measures
– Outside RH: ~72%, Tent RH: consistently at ~62%
– Dehumidifier runs continuously, further reduction currently not possible
– Purolyt has been used since Week 3 (priming & spray) → protection against pathogens and better heat tolerance
– VPD between 1.4–1.5 – perfect for flower development
– Comprehensive defoliation in planning and execution:
– Staggered over 3 days (e.g., Monday to Wednesday)
– Goal: Reduction of excess leaf mass and side shoots
– Plants should stand “naked” to maximize air circulation and minimize mold risk
– Focus is on maximum light penetration and development of healthy, dense buds
– Reduced watering amount (see above) after defoliation to avoid stress
⸻
🌿 Plant Condition & Development
– Flower development is visibly progressing
– Deep green, shiny leaves – no signs of nutrient deficiency or over-fertilization
– Stems upright, internodes well spaced
– Odor development kept deliberately restrained
– Goal: Preservation of trichomes – strong odor development = possible sign of damaged resin heads
– Good horizontal spread through SCROG technique
⸻
đź” Outlook for Flowering Week 5
– Start of UV lighting with 20 min/day
– IR remains continuously active for phytochrome control
– Observation of bud structure, resin formation, and moisture development
– Watering amount remains at 6 L – adjustment possible depending on weather conditions
– Further defoliation only if necessary
