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. 🌱💦🌱💦🌱💦🌱💦🌱💦🌱 🌿Day to day tasks & actions 🌿 🌱💦🌱💦🌱💦🌱💦🌱💦🌱 23.11.25 FW1 – Fed 3l of #1 → 1l runoff 24.11.25 FW2 – Fed 5l of #1 → 2l runoff 25.11.25 FW2 – Fed 5l of #1 → 2l runoff 26.11.25 FW2 – Fed 5l of #1 → 2l runoff 27.11.25 FW2 – Fed 5l of #1 → 2l runoff 28.11.25 FW2 – Fed 5l of #1 → 2l runoff 29.11.25 FW2 – Fed 5l of #1 → 2l runoff 30.11.25 FW2 – Fed 5l of #1 → 2l 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

Once again, this week starts where the former one ended. With the exception of all the cables you can see in the first picture. I dared to install a minimalized version of the Raspi control only controlling the self-built humidifier and one blower/fan combination. I was very pleased to see how easily the simple diffusor can hold optimum VPD as long as temperatures are high and humidity tends to fall below optimum VPD. A single 10 seconds evaporation can hold the level for about 2–3 minutes. I am not pleased to see the Monsanto blowers rather underperform. It’s impossible to reduce humidity or temperature with both running on full speed, while a lifting of the tent door will bring immediate changes. With the Raspi/Arduino success so far*, I am thinking about using old Power Mac fans which are WCM controllable and use 12 V. At least one to increase air intake, and maybe even the blowers. * It wasn’t any problem at all to have the Arduino collect CO2 and soil moisture data, so after some more cable manufacturing (aka helpless soldering), I could extend the Raspi control. I’m still uncertain about the camera module (@trelorny impressed me with his time lapse videos). I don’t want to put the hardware into the tent with its not so electronics friendly climate, already risking some rare outages of the temp/hum sensor. But the camera module cannot be placed far away. So maybe I’ll use the 3A model I own as a spare part as a camera driver. Any maybe, if it works, invest in a better camera module. Mine is generation 1. Oh, and the ladies! Gave them slightly fertilised water yesterday, and even it or the better VPD yesterday or a combination of both make me believe bud growth is a bit more visible today. The smell in the morning when I open the tent to release accumulated humidity is outstanding. They were already thirsty on day 57 again, so pure RO + a bit of tap water until it spilled out of their pot’s bottoms. Many fan leaves turning autumnally now, and the smallest Sherbet suffered a bit from over-fertilisation as I wrote. But it this stage I don’t go for leaf beauty anymore. Just another learning: Don’t use differently sized pots anymore. Hard to feed them individually this way. VPD was mostly in best range yesterday, and I have the feeling it really supports their bud growth. I added an "Evening time" option to my Raspi control that allows the humidity to sink a selected time before lights shut down. That made it possible to have humidity in best range for most of the night time too. They were even dry again on day 58 morning. Another time just water. The blowers cannot cope with the flowers’ smell anymore, and so sometimes my flat cannot hide who shares it with me. Day 60 presents me with a problem: I’ll leave on Friday for a few days. Considering the microscope pictures are not from the tops buds: Would you say it’s safe to give them another week? Problem solved on day 61. Only clean water from now on, and next week will be their last. You won’t see any new pictures for some days now. Me too … Something I wanted to share with you before I leave: I just finished to update my grow box control with a new PWM fan hat that keeps the Raspi cool, while at the same an infrared sensor can now measure real leaf and additional ambient temperature. Setup is much cleaner and more robust now, but I wish my flux would not make the solder stick to the tip of the machine instead of making it flow and stick at the tiny tiny spots I have to hit …

Tuve improvisar y arriesgar una plaga, con unos guias de sauce que tenia de una poda del jardin, no le logre guiar par a toda la carpa pero me servirara para cosnstrastar los resultados, ya se ven muchos mas tricomas consireblamente.

Week 5 flowering for our banana purple punch from fastbuds 420! The buds are starting to get fatter day by day, we continue with our food program. This week again we gave sugar shot, sticky fingers, bloom booster, silica, amino and master root all from xpert nutrients. All good at the moment 🤗

420 Fastbuds Week 2 Veg FBT2305 The two of these are starting off great. The few rust spots stopped and stayed on the couple leafs it showed up on. I feed 500ml of solution every other day. I did start the General Hydroponics 3 part Flora series as well as the Calimagic. On week one I started 1/4tsp per gal ratio every other feed, so far no burn so will probably bump it up this coming week and see how they respond. All in all Happy Growing.

Diese Woche lief alles Problemlos. Dem Haupttrieb wurden weiterhin immer wieder die Sonnensegel entfernt und es wurde ein bißchen LST gemacht um die Fläche etwas besser auszunutzen. Es gab ein Orgatrex / Baktrex Topdressing und prophylaktisch gab es noch mal Culinex gegen Trauermücken.

A ver, la planta va muy bien, crece muy bien, tragando agua sigue igual, al mismo ritmo, cada 2 o 2 dias y medio le hecho sus 3 litros, y a veces riego con 7 para que drene algo. Ahora bien, el amarillo... ¿Porque está tan amarilla!? -Puede ser por haber pecado de ir flojo con los nutrientes. Falta de potasio. -Puede ser por bloqueo por PH o por sales. -Puede ser un hongo. -O puede ser, y es aquí mi teoría jajajaja, que dado que esta planta ya la he cultivado dos veces mas antes, la primera vez, fue bastante mejor que la segunda y pude asegurar el lavado y llegar bien a sus últimas fases y tal (se cagó en el secado que duró 4 dias jajajaja pero bueno, de todo se aprende) y lo curioso, es que en ese primer cultivo, me amarilleo también muuy pronto, con las mismas manchas y de aquí mi teoria: este genotipo alarga el uso del nitrogeno hasta fases avanzadas de floracion y además empieza a tirar de reservas antes de lo habitual (lo cual explicaría que esta es una de esas plantas que en una semana ha madurado y no te das cuenta) y dado que en floracion el ph se baja, yo lo fui bajando conforme arrancó el stretching por lo que le fui limitando las reservas de nitrogeno antes de lo que ESTE GENOTIPO pide, y de ahí el amarillenteo de la mayoria de las hojas. Como tengo todavía varias semillas mas de esta, seguiré plantándola a ver hasta donde podemos llevarla y gracias a cosas como estas, ir aprendiendo por el proceso. PD: tengo ramas atadas o apoyadas a la pared por que se caen del peso xD

The best taste under the sun, great color of buds, unforgettable gorillas for me;) After quite a long fight with high temperatures and lack of support in the form of boosters, I am happy with the final result.

it grows and grows and grows. it looks very healthy and strong. the changeable weather doesn't bother it at all. the first small pistils can be seen. it gets a nice nutrient mix from biobizz root and grow.

I cut another part of the girls, and the total is even greater than the first part! We wait another week for the final sums, but right now the flavor is unique.

Day 9. All is running very nice. Happy with light performace a lot. Girls missed wind a bit, but i cant make it faster, because of neighbours and sound, so i took humidity dome away. TSL2000 runs 40 cm away and on 40% output. Girls get daily shower , try to keep some wet cloth to maintain humidity. Happy Growing !!!
