FERMAKOR BARREL MIX – BASE IN USE (Testing on the Fantasy Feast girl we pulled out of another diary https://growdiaries.com/diaries/274722-grow-journal-by-yan402 ) (FERMAKOR BASE SYSTEM KOH VERSION diary https://growdiaries.com/diaries/278391-grow-journal-by-yan402) (Urea & Micros on the way — first week running without them) 🍶💧🍶💧🍶💧🍶💧🍶 💧 30 L Barrel – Current Working Mix 🍶💧🍶💧🍶💧🍶💧🍶 Step 1 – Calcium Nitrate (Part A) 7 L warm water (~35–40 °C) → added 45 g Calcinit, stirred until fully clear. That’s the calcium + nitrogen backbone for the feed. Step 2 – FERMAKOR PK Base (Part B) 15 L water in the main barrel → added 30 ml FERMAKOR PK Concentrate, mixed well. This forms the main P + K part of the formula. Step 3 – Combine Solutions Slowly poured the Calcinit mix into the barrel while stirring — no reaction, still crystal clear. That confirms the mix is stable and precipitation-free. 🌿 Step 4 – FPJ / FFJ Batch Added 30 ml homemade FPJ (fish + veg batch) ≈ 1 ml/L. Color shifted to a light-amber tone — looks alive and active. 🍋 Step 5 – Citric Acid Balance Added 1 tsp citric acid after everything was blended to fine-tune pH and help chelate micros later on. 📦 Step 6 – Top Up & Check Filled to the 30 L mark with plain water → pH tested with drops, showing yellow-green — roughly 5.8 – 6.0 range. Nice clean look, stable smell, no residue. 💧 Current Base Ingredients (Active Mix) Warm Water ≈ 22 L total Calcinit 45 g → N + Ca foundation FERMAKOR PK Base 30 ml → P + K support Citric Acid 1 tsp → Chelation + pH balance FPJ / Fish Emulsion 30 ml → Organic enzyme booster Result: clean amber mix, mild and balanced. I’ll let this version run for a week before adding anything. 👀👀👀👀👀👀 Observations and changes 👀👀👀👀👀👀 27.10.25 VW27 noticed some min burnt tips so I decreased Calcium Nitrate 45 to → 40g, decided to add two more elements micros and Epsom salts just to make sure they got everything, Fetrilon Combi 1 (Micros): 0.5 g, Epsom salts: 8 g 28.10.25 VW27 she seems devoid of any deficiencies, seems ready for the flip to 12/12 02.11.25 VW27 girl is looking good so I decided to stop making daily videos and do a standard once a week update. 09.11.25 aVW28 7 days since flip,stretch in full swing, first pistils showing, leaf color deep and healthy. Slight tip burn early week → gone after pH stabilized. Feed stayed clear, no residue, roots clean and sweet-smelling, did what I hope is a last cleanup and pruning🎥 10.11.25 VW29 added Phosphoric acid pH down to the schedule for flowering stage. 14.11.25 FW1 FERMAKOR PK Micros 40 → 50 ml 23.11.25 FW2 got some burnt tips, observe and act accordingly in case it worsens, diluted by 25% for this week. 05.12.25 FW3 about 2 weeks ago Calcium Nitrate 35 g → 25 g, FERMAKOR PK Micros 50 ml → 60 ml 12.12.25 FW4 Calcium Nitrate 25 g → 20 g, FERMAKOR PK Micros 60 ml → 80ml 16.12.25 FW4 Calcium Nitrate 20 g → 17 g, FERMAKOR PK Micros 80 ml → 110 ml 20.12.25 Calcium Nitrate 17 g → 15 g 26.12.25 Ffj fpj 30 →0ml 05.01.26 last feed LST and trimming, harvest is end of the week 09.01.26 🌱💦🌱💦🌱💦🌱💦🌱💦🌱 🌿 Day to day tasks & actions 🌿 🌱💦🌱💦🌱💦🌱💦🌱💦🌱 Fed about 5l a day of #1 and on the weekends I do a pure FERMAKOR PK flush 2l runoff (*RUNOFF reused for tomato plants) 💧💧💧💧💧💧💧💧💧 🌱 Nutrients in 30 L #1 – FERMAKOR (progression kept) 💧💧💧💧💧💧💧💧💧 Calcium Nitrate (Calcinit / Nitcal): 45 → 40 g → 35 g → 25 g → 20 g → 17 g → 15 g = 1.50 g/L → 1.33 g/L → 1.17 g/L → 0.83 g/L → 0.67 g/L → 0.57 g/L → 0.50 g/L = 207 ppm N / 253 ppm Ca → 184 / 225 → 161 / 197 → 115 / 141 → 92 / 112 → 78 / 96 → 69 / 84 PK Concentrate (FERMAKOR Base): 30 → 40 ml → 50 ml → 60 ml → 80 ml → 110 ml = 1.00 → 1.33 ml/L → 1.67 ml/L → 2.00 ml/L → 2.67 ml/L → 3.67 ml/L → balanced 1:1 P:K + light micros (from extract) Home-made FFJ/FPJ (Fish + Veg): 30 ml → 0 ml = 1.00 ml/L → 0.00 ml/L Epsom Salt (MgSO₄·7H₂O): 8 g = 0.27 g/L → ~26 ppm Mg + ~35 ppm S Fetrilon Combi 1 (Micros): 0.5 g = 0.017 g/L → Fe 0.7 ppm · Mn 0.7 ppm · Zn 0.3 ppm · Cu 0.3 ppm · B 0.1 ppm · Mo 0.02 ppm Phosphoric Acid (pH down) + Citric Acid (chelation): as needed → First set pH with phosphoric acid, then add a little citric only if you want extra chelation Target pH: 5.8 – 6.0 (drop test yellow-green) 📦 TOTAL (corrected): Liquids (PK + FFJ/FPJ): 60 → 70 → 80 → 90 → 110 → 140 → 110 ml per 30 L = 2.00 → 2.33 → 2.67 → 3.00 → 3.67 → 4.67 → 3.67 ml/L Solids (CaNO₃ + Epsom + Fetrilon): 53.5 → 48.5 → 43.5 → 33.5 → 28.5 → 25.5 → 23.5 g per 30 L = 1.78 → 1.62 → 1.45 → 1.12 → 0.95 → 0.85 → 0.78 g/L YouTube Link: https://youtube.com/-m8h?si=A7x4Zlr2kj-_ga31
