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.

Growing like a weed!lol

02/23/2022 Lots of stretching this week,not much to say so I let the pics and videos talk for them selves🙏🏻 Enjoy Grape Skunk tall and lanky one I'm loving! I will number her for future reference. Biscotti Skunk has some droopy leaves, it's watering day.

7-16 This thing blows my mind. She smells like overripe pineapple. Frost coming in. Mad stacking. The leaves can be floppy but otherwise look healthy. It’s really hard to take a picture of how huge these colas are coming in. Never thought I could grow big buds like this with my low watt LEDs! 7-19 Fattening up and reeking more with some orange hairs coming in.

Hey guys, Another Explosive week has passed and the plant seems to not stop growing, I have some side branches reaching 80cm while the main branch stopped at 68cm. I really hope it can produce nice buds. At the moment it still a little bit 'empty' hoping week 7 will make the flower explode, I really hope so... For now it's all, stay tuned and stay high nice people!

The second week of flowering, last bigger cut, I accidentally broke one of the smaller top ones 😔😤, the girl is doing well 👍 Day 63: the eighth week went without major changes, the girl shows no shortcomings and grows nicely.

Week 3 (14-2 to 20-2) 14-2 Watering: Gorilla Kush#1: 114 ml. Gorilla Kush#2: 117 ml. 15-2 Watering: None. No pictures. 16-2 Watering: Gorilla Kush#1: 119 ml. Gorilla Kush#2: 121 ml. 17-2 Watering: None. 18-2 Watering: None. Today i will transplant the plants, i will mix 70% Coco coir with 30% Perlite. The plants go into 18L AutoPots. I use the Airdome combined with an airstone. I covered half of the airdome with coco, and the remaining half with clay pebbles. The rest of the 18L pot filled with the coco mix, and the plants. I gave both plants a 1.5L topfeed, and into the tent they go! The light is at 70% strength, with a distance of 60 cm. 19-2 Temperature: 25.7 degrees (lights on) 20.4 degrees (lights off) Humidity: 64% (highest) 45% (lowest) Watering: None. Light strength reduced to 60% 20-2 Temperature: 25.4 degrees (lights on) 20 degrees (lights off) Humidity: 64% (highest) 50% (lowest) Watering: None.

Eyes on bud swelling and trichome cluster ripen ratios /./ harvest prep //

What do you think? What is the problem of the plant? Did it suffer? Or is near to the end?

Week 7 VEG – The White OG (Seedsman Seeds) This week was all about shaping, training, and refining. We stepped into the art of mainlining, guiding her structure into perfection while giving her the space to shine. A little seduction, a little discipline, and a whole lot of plant love. 😏✨ 🌿 Mainlining: The Art of Balance Mainlining isn’t just training—it’s sculpting. By evenly distributing energy and growth, we create a strong, symmetrical plant that’s ready to thrive. 🔹 Topped and trained – Ensuring equal energy flow and balanced growth. 🔹 Leaving two nodes per branch – Structuring her for a powerful, even canopy. 🔹 Guiding her gently – With the right support, she bends but never breaks. 🍃 Defoliation: Light, Air, and Growth Less is more when it comes to defoliation! The goal? More light penetration, better airflow, and a happier plant. 💡 Removing lower leaves – Redirecting energy to the most important growth points. 💨 Improving airflow – Keeping her environment fresh and reducing moisture buildup. 🌞 Allowing deeper light penetration – No more shadows, just pure, even growth. 🔥 The Studio Treatment This week, she got the VIP studio treatment—out of the tent, under the lens, and shining against that sleek black background. Sometimes, you just have to appreciate the beauty of the work in progress. Tent Conditions & Feedings 🔸 Temps: Around 18°C – a little chilly, but she’s handling it like a champ. 🔸 RH: 60% – Keeping that balance for steady veg growth. 🔸 Feed: Still running Aptus Holland’s organic-mineral lineup—strong, steady, and full of potential. 🔸 Lights: Future of Grow LED, 200 PPFD—keeping her compact and thriving. 💚 Shoutouts & Love Huge thank you to the amazing sponsors and supporters! 🌱 @Seedsman @AptusHolland @FutureofGrow @TrolMaster @ProMixSoil @Cannakan 🌍 Special shoutout to the entire Grow Diaries family, the followers, the lovers, the haters—this one’s for you all! 👀 New episodes dropping weekly on YouTube!

I did a 5 day flush and 5 days of 24 hour light before harvest. Dried for 16 days with 60% humidity

Decided to turn on my bloom lights on my Optic 2 Gen 3 LED which incrediblely increased the temp so lucky 🍀 I have a carbon filter from ac infinity “4 and a inline fan from Vivosun which really work great to suck the stagnant hot air out of my 32”x32”x72” tent. Other then that have been feeding these girl Urb& liquid seaweed and they seem to be loving it. Would love to make a compost tea soon.

Lot of leaves taking forever to trim

Howdy, So this last week has been about learning, quickly. Plant 2 has been suffering from yellowing, I noticed that at first it was a darker green than plant 1 - (first signs of Mg deficiency I have since learned). As plant 1 was doing so well until a few days ago, I originally assumed that plant 2 was just a bit of a slacker. I think basically it is more susceptible to PH differences than plant 1. First mistake was not knowing about the benefits of PH range... What I did not know earlier in the week is that Mg and Ca are only absorbed efficiently at 6.0 and above, my OCD kicked in and I refused to let the PH wander above 5.7; as from what I have read in forums, 5.7 is the sweet spot. Main lesson from last week is that I'm not going to be so anal about PH levels, I will let the PH rise to 6.3 before I drop it back down to 5.7, this will give the plants and window of time to grab hold of some well deserved CalMag before I drop it back down so it can retrieve some Mn and P if it needs any. My plants told me they were in need of Calcium over a week ago, but I naively thought that maybe I spilled a droplet of water on one of the leaves, and that caused it to burn. As I was adding CalMag+ to the solution when I replenished the reservoir. My second mistake was panicking... After realising above, I bombed the nutrient solution with 35ml of Cal Mag, bringing up the PPMS to 460, this subsequently gave the strongest plant nutrient burn. On top of this, I gave both plants a foliage spray during lights out with some diluted CalMag as well. So anyway, the main thing I have learnt is when the plants are ill, its probably best to take it easy, do a res swap at the very worst and concentrate on my PH levels first before throwing more variables into the fray. Positive notes: Plants 1 & 2 is now working on their 5th node, I know I am technically allowed to top at this point, but I am going to wait until they are working on their 7th before doing anything, this way I will be able to tell if the new growth is looking healthy, and my investigations are correct. I have now installed a Hailea 150a, with a submersible pump, this is now keeping the reservoir at 20ºc and its keeping the nutrients well mixed, I'll post a video later this week showing the set up. The roots at the top look a little dark, but I have done a sniff test and they don't smell at all, I think it is just where some of the tea has built up where the bubbles meet the air. Roots do seem rather large, maybe they have stretched so far looking for Mg and Ca :P Decided against increasing PPMS, going to do another week, so 5 weeks veg, gives the ladies some time to recover. Trimmed the burns off of leaves mainly so I can keep a track to see if damage is continuing. Anyways, I hope the above makes sense and draws other newbies attention towards PH ranging for hydro; I have posted a pic which shows the PH range for each important element. Thanks! 😊

Last daaaays 😍😍 Im trying not to rush the flush and I rather wait a few more days to bring this ec right down. Still looking pretty healthy and not much yellowing yet. Note to myself : stop thinking of cutting stop thinking of cutting ....

A big hello to My fellow growers & friends 👋 Finally the big day has come, as of today at 7pm i will turn out the lights and start five (or so) days of darkness for the four lovely Killer Kush girls. The trichomes are reaady (in my opinion), it took a little bit longer than expected but it's the first time I grew photoperiods. Super happy how it turn out tought 😍 Here are the transcripts of how my week did go through: 12.09. My Ph is 5,95 and the girls drunk very little last night so i add some 4 ml. of Ph+ to the reservoir PH: 6,15 EC: 3.8 15.09. I thought that this day would be my last day of light for the plants but after heavy consideration and observation of the flowers i decided to give them 5 more days and with it some more nutrients adding: Jungle Indabox :A: 25ml. B: 75ml. M: 50ml. Plagron green Sensation: 82ml. Sugar Royal 33ml. Canna Cal Mag: 70ml. Hesi Powerzyme: 70ml. PH: 6,2 EC: 4.1 Yesterday on 18.IX. I came down to the basement and wound aa puddle of water (see the pictures) it was not system leak, sometimes my basement just takes on water...obviously it's more moisture is very unwelcome at this stage. I plugged in my dehumidifier and after couple hours the puddle was gone... you can see in the picture how much Watts my system is using all together with a dehumidifier included. That's it for this week I hope everyone had as good a week as i did, hopefully see you next week 😇 all the best to you my friends and keep it growing 💪
