yan402 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 Status
First day feeding the Fantasy Feast girl with this base mix.
Too early to tell how she’ll react, but so far everything looks clean and balanced.
Ca + N from Calcinit and P + K from FERMAKOR should be plenty for a gentle start.
Citric + FPJ round it off nicely.
We’ll see how she takes it over the next few days before deciding if she even needs the urea and micros.
💧 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.

💧 Nutrients in 30 L #1 (Veg Strength)
🍶💧🍶💧🍶💧🍶💧🍶
💧 Calcium Nitrate (Calcinit / Nitcal): 45 g
= 1.50 g/L → ≈ 225 ppm N + 150 ppm Ca
🍶 PK Concentrate (FERMAKOR Base): 30 ml
= 1.00 ml/L → balanced 1 : 1 P : K support
💧 Home-made FFJ / FPJ (Fish + Veg Batch): 30 ml
= 1.00 ml/L
🍶 Citric Acid (Chelation & pH Balance): 1 tsp (max)
= 0.33 tsp/L → add only after checking pH
💧 Target pH: ≈ 5.8 – 6.0 (drop test – yellow-green zone)
📦 TOTAL: ≈ 105 ml / 45 g inputs per 30 L (≈ 3.5 ml / g per L active mix)

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

@tantrumrage, MAXIMUM a week lol, depending on ffj/fpj inputs or whatever kind of organic you might use in combination, 3rd day I usually have to adjust my pH again.
✌️♥️
@Natrona, Yeah I think so to, nutrients seem to be working fine for now, even if it doesn't end up perfect by the next grow or the grow after I'll be spending pennies per grow instead of the cutthroat prices they charge for bottled nutes.
Thanks for dropping by sister 🙏, you are always welcome in my garden ✌️♥️
@Green_claws, I love this strain bro, really dense buds been through hell and back, started indoors "thrown" outside due to space reasons lived from the runoff of my indoor plants for at least 2 months experimented on and I probably forgot a couple of things I have done to them lmfao, thanks for dropping by bro, much love 😘✌️♥️
