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 🌱💦🌱💦🌱💦🌱💦🌱💦🌱 🌿Day to day tasks & actions 🌿 🌱💦🌱💦🌱💦🌱💦🌱💦🌱 16.11.25 VW29 – no feed no water 17.11.25 FW1 – Fed 3l of #1 → 1l runoff 18.11.25 FW1 – Fed 3l of #1 → 1l runoff 19.11.25 FW1 – Fed 3l of #1 → 1l runoff 20.11.25 FW1 – Fed 3l of #1 → 1l runoff 21.11.25 FW1 – Fed 3l of #1 → 1l runoff 22.11.25 FW1 – Fed 3l of #1 → 1l runoff 23.11.25 FW1 – Fed 3l of #1 → 1l runoff 🍶💧🍶💧🍶💧🍶💧🍶 💧 Nutrients in 30 L #1 Veg — FERMAKOR 🍶💧🍶💧🍶💧🍶💧🍶 💧 Calcium Nitrate (Calcinit / Nitcal): 45 g → 40 g → 35 g = 1.33 g/L → 207 ppm N + 253 ppm Ca = 1.17 g/L → 183 ppm N + 224 ppm Ca (current) 💧 PK Concentrate (FERMAKOR Base): 30 ml → 40 ml → 50 ml = 1.00 → 1.33 → 1.66 ml/L → balanced 1:1 P:K + light micros (from extract) 💧 Home-made FFJ/FPJ (Fish + Veg): 30 ml = 1.00 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): → First set pH with phosphoric acid → Add a little citric only if extra chelation is needed 💧 Target pH: 5.8 – 6.0 (drop test yellow-green) 📦 TOTAL Inputs: 60 ml → 70 ml → 80 ml / 48.5 g per 30 L = 2.00 → 2.33 → 2.66 ml/L + 1.62 g/L (current) YouTube Link: https://youtube.com/-m8h?si=A7x4Zlr2kj-_ga31
