π§ 30 L Barrel β Current Working Mix
πΆπ§πΆπ§πΆπ§πΆπ§πΆ
Step 1 β Calcium Nitrate (Part A)
7 L warm water (~35β40 Β°C) β added 45 g Calcinit, stirred until fully clear.
Thatβs the calcium + nitrogen backbone for the feed.
Step 2 β FERMAKOR PK Base (Part B)
15 L water in the main barrel β added 30 ml FERMAKOR PK Concentrate, mixed well.
This forms the main P + K part of the formula.
Step 3 β Combine Solutions
Slowly poured the Calcinit mix into the barrel while stirring β no reaction, still crystal clear.
That confirms the mix is stable and precipitation-free.
πΏ Step 4 β FPJ / FFJ Batch
Added 30 ml homemade FPJ (fish + veg batch) β 1 ml/L.
Color shifted to a light-amber tone β looks alive and active.
π Step 5 β Citric Acid Balance
Added 1 tsp citric acid after everything was blended to fine-tune pH and help chelate micros later on.
π¦ Step 6 β Top Up & Check
Filled to the 30 L mark with plain water β pH tested with drops, showing yellow-green β roughly 5.8 β 6.0 range.
Nice clean look, stable smell, no residue.
π§ Current Base Ingredients (Active Mix)
Warm Water β 22 L total
Calcinit 45 g β N + Ca foundation
FERMAKOR PK Base 30 ml β P + K support
Citric Acid 1 tsp β Chelation + pH balance
FPJ / Fish Emulsion 30 ml β Organic enzyme booster
Result: clean amber mix, mild and balanced.
Iβll let this version run for a week before adding anything.

Observations and changes
ππππππ
27.10.25 VW27 noticed some min burnt tips so I decreased Calcium Nitrate 45 to β 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 β gone after pH stabilized.
Feed stayed clear, no residue, roots clean and sweet-smelling, did what I hope is a last cleanup and pruningπ₯
10.11.25 VW29 added Phosphoric acid pH down to the schedule for flowering stage.
14.11.25 FW1 FERMAKOR PK Micros 40 β 50 ml
23.11.25 FW2 got some burnt tips, observe and act accordingly in case it worsens, diluted by 25% for this week.
