FERMAKOR BARREL MIX – BASE IN USE

🍶💧🍶💧🍶💧🍶💧🍶
💧 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

💧 Nutrients in 30 L #1 Veg — FERMAKOR
🍶💧🍶💧🍶💧🍶💧🍶
💧 Calcium Nitrate (Calcinit / Nitcal): 45 → 40 g
= 1.33 g/L → 207 ppm N + 253 ppm Ca
🍶 PK Concentrate (FERMAKOR Base): 30 ml
= 1.00 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
🍶 Citric Acid (Chelation & pH Balance): ½ tsp (max)
= 0.16 tsp/L → add only after pH check
💧 Target pH: 5.8 – 6.0 (drop test yellow-green)
📦 TOTAL: 60 ml / 48.5 g inputs per 30 L
= 2.00 ml/L + 1.62 g/L
