Critical Auto - First Cannabis Grow

Hurtcules 🛠️ Setup & Environment Lighting: Samsung LM301H @ 240 PPFD → increased to 290 PPFD by Day 16 Light Schedule: 20/4 Temp: 75°F RH: 75% VPD: ~0.6–0.7 🌱 Seedling Growth & New Germination April 2 (Day 9): The replacement seed was planted directly into the top-left pot (no paper towel this time). Main 3 plants: Continued steady development with widening serrated leaves and strengthening stems. April 7–9: The new seedling finally emerged — healthy, but naturally smaller than the others. 💧 First Feedings Introduced Starting April 5 (Day 12), the 3 main seedlings began receiving light nutrient doses: Feeding Formula (Days 12–14): Volume: 300 mL per plant Grow A: 0.66 mL Grow B: 0.66 mL CaMg: 0.66 mL Cleanse: 0.5 mL pH: 6.0 Water: RO with 24 PPM baseline Feeding Formula (Days 15–16): Volume: 300–350 mL per plant Grow A: 0.66 mL Grow B: 0.66 mL CaMg: 0.66 mL Cleanse: 0.5 mL EC Target: ~0.8 pH: 6.0 📌Keep in mind that these feedings are per the volume of RO water to be used. I updated the journal with that conversion in mL/L 📌 The replacement seedling received only plain pH 6.0 water during this period. 🔎 Observations Main 3 plants developed consistent vertical growth, tight node spacing, and healthy leaf posture. Leaf color remained strong and vibrant green throughout the week. No signs of overwatering or burn from first nutrient applications. Light was increased to 290 PPFD by Day 16 to support growing canopy height. ✅ Wins First feedings were a success — no nutrient burn or pH issues. Light was dialed in based on plant growth response. The replacement seedling emerged healthy (though later than expected). All 3 main plants well on their way to entering vegetative growth.

Hurtcules 🛠️ Environment & Lighting Temp: 75–78°F Humidity: 75% RH (stable) VPD: ~0.6–0.7 Light Intensity: Increased from 290 → 320 PPFD Light Height: ~27" above canopy ✂️ Training & Maintenance Topping: April 13 (Day 20): First two larger plants topped. April 16 (Day 23): Third mature plant topped. LST: Began on Day 20 and continued through the week. Plants gently spread outward to promote light penetration and more even canopy. Defoliation: Fan leaves blocking lower growth were removed gradually for airflow and light exposure. 💧 Feeding Schedule & Details Daily Volume: 450 mL per plant (3 plants) Total Daily Mix: 1350 mL Nutrient Dosing (per full batch): Grow A: 1.5 mL Grow B: 1.5 mL CaMg: 1.5 mL Cleanse: 1.1 mL pH: 6.0 Target EC: 0.95–1.0 Target PPM: 500–525 📏 Conversion to mL/L for Reference: Mix was made for 1350 mL total, so conversion to mL per Liter is: Nutrient Amount Used mL/L Equivalent Grow A 1.5 mL 1.11 mL/L Grow B 1.5 mL 1.11 mL/L CaMg 1.5 mL 1.11 mL/L Cleanse 1.1 mL 0.81 mL/L ✅ This was scaled to support controlled vegetative growth while preventing buildup in coco. 🌱 Seedling Care Top-right seedling continued to establish roots and early leaves. Watered with 60 mL plain pH 6.0 tap water each day — no nutrients yet. ✅ Wins This Week Plants responded very well to topping and LST, showing no droop or shock. Strong node spacing and branch formation across all three mature plants. EC, PPM, and pH levels stayed within target with each feeding. Canopy evened out, prepping plants for transition into pre-flower soon.

Hurtcules 🛠️ Environment & Lighting Temperature: 78°F (raised slightly this week) Humidity: 70% RH (held stable) VPD: ~0.6–0.75 Light Intensity: Increased to 340 PPFD to match plant height Light Height: ~24" above canopy ✂️ Training & Maintenance LST Continued: Daily adjustments to further widen the canopy and expose lower nodes Fan Leaf Removal: Targeted defoliation to improve airflow and light penetration Plant Posture: Notable improvement in structure and leaf turgor following feedings 💧 Feeding Schedule & Nutrient Details For the 3 Mature Plants: Daily Volume: 450 mL per plant → 1350 mL total Nutrient Mix (per full batch): Grow A: 1.6 mL Grow B: 1.6 mL CaMg: 1.6 mL Cleanse: 1.1 mL pH: 6.0 Target EC: 1.0–1.05 Target PPM: 500–525 📏 Converted to mL/L Reference: Nutrient Amount Used mL/L Equivalent Grow A 1.6 mL 1.18 mL/L Grow B 1.6 mL 1.18 mL/L CaMg 1.6 mL 1.18 mL/L Cleanse 1.1 mL 0.81 mL/L 🌱 Seedling Care (Top-Right Plant) Deficiency Response Initiated (Day 12 – April 23): Fed with 300 mL solution at 0.66 EC, pH 6.0 Nutrients: Grow A/B/CaMg @ 0.25 mL each + Cleanse @ 0.2 mL Goal: Begin correcting early yellowing and reintroduce baseline nutrition after prior RO-only watering Monitoring for response ✅ Wins This Week All 3 mature plants showing vigorous response to LST and feeding Even canopy formation now developing across the tent Environmental controls remained dialed in with stable temp/RH Seedling recovery plan deployed Light intensity increased without signs of stress or leaf curl

Hurtcules 🛠️ Environment & Lighting Temperature: 78°F (stable throughout the week) Humidity: 70% RH (maintained for optimal VPD) VPD: ~0.6–0.75 Light Intensity: Increased midweek to 360 PPFD Light Height: Maintained at ~24" above canopy ✂️ Training & Maintenance LST: Continued daily adjustments to spread canopy and improve node spacing Defoliation: Minor defol performed on Days 35 and 38 to increase airflow/light to inner sites Focused on removing large fan leaves shading lower branches Posture/Health: Two largest plants now showing roots at pot base (early rootbound indicator) Plants maintaining excellent turgor and leaf color following feeds 💧 Feeding Schedule & Nutrient Details For the 3 Main Plants: Daily Volume: 500 mL per plant → 1500 mL total/day Nutrient Mix (per 1500 mL batch): Grow A: 2.0 mL Grow B: 2.0 mL CaMg: 2.0 mL Cleanse: 1.2 mL pH: 6.0 PPM: ~575 EC: ~1.1 🌱 Seedling Care (Now Day 28 Since Emergence) Feeding Volume: 400 mL daily Nutrient Mix (per batch): Grow A: 0.4 mL Grow B: 0.4 mL CaMg: 0.4 mL Cleanse: 0.2 mL PPM: ~370 pH: 6.0 Notes: Seedling continues strong upward growth Early signs of upward stretch and structure developing No LST or defol performed this week ✅ Weekly Wins LST successfully maintained low, wide canopy on all three main plants Early flowering signs spotted on Day 38 — pistils forming Feeding regimen optimized to match light intensity increase (now 360 PPFD) Roots reaching base of fabric pots indicate solid vegetative growth Seedling developing evenly and progressing toward mid-veg structure
