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.

Thanks for stopping by.. Please hit the like button if you like what you see and ill be sure to check you out too Growmies 🌱 Week 6 of flower .. sooo nearly there. Last week developed a calcium deficiency and some of the leaves are deteriorating 😡 Added Calgel(CalMag) at a 0.3ml per L dose hopefully there perk up abit again, Will also be adding a NPK booster this week as there starting to fade quite abit early, Dehumidifier is doing its job dropped the humidity around 15-20% Temps 21-28 ✅ Humidity 45-55 % ✅ Overall happy with the progress this week now to focus on getting through this deficiency 👍👍👍

Around 3 weeks to go She looks great and smells fantastic

Note: At time of writing the Runtz has had 2 weeks cure, will update the review and rate it after 2+ months cure. Hermied a bit, has very few seeds so not too bad. Growth review: - vigorous grower during veg - solid stretch - medium internode distance - small sized buds - lower buds not too airy - very easy/not fussy - medium amount of smell - 80+ days flower (12/12) in hydro DWC under full spectrum led - responded well to various lst techniques Ease of growth rating: 9/10 General note: --> For me personally this strain NEEDS a good cure and is not worth smoking yet... It has a bit of a citrus grassy (not hay) taste, with some 'special' fruity smells to it that remind a bit of grapes/cassis. When grinding/opening the curing pots there is a pretty dank heavy weed smell so I think the quality will come out after a few months of cure... In its current state not worth smoking for the taste or effect after 14 days cure. --> Currently the effect is not very strong, easy to handle and I need a lot to feel a bit. The effect lasts for short compared to the average strains I smoke. Should develop more character with a longer cure. Hash making notes: - water extraction of the trim yielded 16g of hash (45mc-220mc) - rosin has a bit too much of a weird spicy grassy taste which make it a bit unpleasant, waiting till the buds improve with cure to try again - rosin color at 80c is yellow/white/beige creamy waxy, with hard consistency - rosin color at 95c is golden with hard consistency

What a fun experience! This was my first time trying a mixed grow style of synthetics and organic. I think I may have found my new go-to strategy. This definitely wasn't a perfect run by any means - as a matter of fact, I botched the feedings earlier in her life. However this grow definitely taught me a lot more about how to treat this strain properly. Now I'm running her clones in the 3x3x6. So the legacy will continue! Let's see how this strain does during the summer months! Cheers everyone! This has been an awesome grow. What I'm lacking in yield, I yet again make up for in quality. And I don't think yield will be an issue with the clones, they're week 6 veg - and quite massive! - RWI out!! 😁 😶‍🌫️🤑

Last week for these strudlesss! 🔥 I chopped the small one a few days ago and has been drying out was frosty as!! Few more days and stems should be snappy Other 2 look fatty! Covered in trichomes! Can see a couple of Amber's so Overdrive this week and then onto final flush with Flawless Finish. Smell is really good! Cakey sweet bakery! 😋 Temp 24 day 19 night Humid 45% 👊👽👊

Comenzando lst día 15

8/19 Rained again last night. No damage but medium is drenched. The 9lb kush I've been struggling with seems to be improving. I spent a lot of time on her yesterday and at least an hour this morning defoliating and pruning her. New growth and flowers look promising. I'm cautiously optimistic. I defoliated what needed it. I needcto qpplyvorganocide again. I can see random signs of septoria leaf spot. I really have been off my fame lately. I'm back on it now. This week the garden will be rearranged and I'll pull that big GDP back and better support the blueberry for flower. That NYCSA is a beast. It's resilient as all hell and just continues getting bigger and fuller. Despite pr9blems in the garden this girl seems absolutely fine. At least I don't have that defeated feeling anymore. I've got flowers on a few different plants. I'll try to get a couple pictures. I may take rapacaps advice and add a cheap plastic roof for later flower. I'm not sure if the explosive flower growth is due to the liquid kool bloom but I think I'm going to switch back to tiger bloom as it works better with the other nutes. I'll jeep this updated but I've got work to do. 8/20 Well it Rained again last night. This is getting discouraging. Now my other 9lb kush has the bottom branch all droopy like there's a borer or something. Realistically with the temp swings and the weather I think it's a firm of root rot or pythiym damage which isn't good. I posted pictures of the stalks and would be grateful if anyone has any advice. I'm go8ng back down to look again for a borer hole but i didn't see one. What it looks like to me is that the petroleum jelly I put on the stalks (to battle ear wigs) seems to keep them moist or something inviting mold or fungus. I'm kind of at a loss. I don't really know where to go from here. I don't know if I should just replant the severely damaged plant away from the rest of the grow, bag it and get rid of it or leave it be and hope for the best. I certainly don't want anything spreading. I'm getting tigerbloom today as my plants still need to eat and I'm nervous about the liquid kool bloom. It's probably fine but still. I'll update after I put in more work and research more today. Any advice helps. UPDATE: No borer holes. The stalk looks fucking horrible. It's supposed to rain today. I'm going to give it one more day then I'll amputate that branch and get rid of the other plant if I don't see an improvement. Perhaps I'll plant it in the ground. Don't really know what to do. Family bar b que today so my options are limited. 8/21 FED TWO GALLONS TO THE GARDEN. ONLY USED .5TSP/GAL OF LIQUID KOOL BLOOM. Did not feed dieing plant. Back to super hot weather 80° at 9am. Did a lot of research last night. I also went to several commercial growers and asked advice. What I came up with was a fusarium infection of pythiym infection (Crown rot). I looked at all my stalks and they all have bark and are darker where I applied the petroleum jelly. I'm also NEVER using DE again. It fucking ridiculous amounts of water. Everyone swears by it bit it's not going in my garden again. Since use I can just watch water sit right on the GD soil. I tried to get some examples of what I'm talking about with the stems. I amputated that lowest bottom branch I trained (which was huge). I didn't have time to dispose of the other plant before my wife's doctor's appointment. I'll update when I go back over. I'm sure this won't help and may hurt but I used Bee Safe 3 in 1 on the wound and around the stalks of the plants I saw discoloration on. I didn't touch the NYCSA even though I see some discoloration. I may just be seeing things. That plant I'd super healthy and I don't want to risk losing it. It doesn't seem to have the stem rot like the others. At least I'm not the only one having problems. I hears some pretty bad stories. Still. I'm heart broken. I'll keep this updated after I go back over. FUCK. I MAY just go back to indoor. UPDATE: Got back from the appointment and the rest of the plant was all droopy just like the other 9lb kush (and the branch amputated). I wondered about that because other branches looked worse. I got the totally dead 9lb kush out and found some root rot. AFTER wheeling the bag out I found earwigs and other insects where the bag had been. Awesome. I used h202 to try to wipe down anything that looked Fingal in the stem. It sucks because it seems like that liquid kool bloom pushed them over the edge into flower. Cotton balls where there was nothing. So that's both my 9lb kush plants and the largest plant of the year the GDP that have all bit the dust. If you grow cannabis you know how I'm feeling. I KEEP TRY8NGVTO UPLOAD THE MINUTE VIDEO I TOOK BUT I CLICK ON SOMETHING ELSE AND IT DISAPPEARS. WIFI SLOW. HAVE TO WAIT FOR 5G 8/22 What do I say? Fusarium? Pythium? Stem rot? I'm going to have to get a tent to do some indoor to get the medicine I need for me and my wife. I took the last 9lb kush out and disposed of it. Well it's still in the bag. I'm hoping maybe it might come out of it (beyond hope and far away from the others (but I'm going to toss it today). This blows so hard. Flowers are just starting to develop. I like the liquid kool bloom. It seems to make flowers explode when there was none before. At least on the plants I have left. Actually even the dieing ones started flowering. I'm really concerned considering that one plant (at least) has septoria and every plant has that petroleum jelly on it. Cautio to people that use that. It seems thats where the rot started or is. In spots I spread the petroleum jelly. Anyway my NYCSA has the smallest amount of "funky looking stuff on the stem" so I'm hoping it will make it. Cotton balls starting to appear. If I lose the whole fucking crop I'm gonna go ape shit. UPDATE: Spoke with a few others and did more research. I removed my braces on the bottom of all the plants. It looks like the pjelly and the brace allowed for some type of contaminate. Other growers think I'm being too bleak. They think things will turn out okay. They are more knowledgeable about cannabis than me but I'm with these particular plants everyday. They're probably right and my anxiety is just getting g to me. It's scary seeing a healthy plant completely die in such a short time. After removing the other 9lb kush I could easily see extreme rootbound roots still too the size of the 1 gallon they came in. The bag was PACKED FULL of tight roots so they definitely made it down. The plant however just fell over when I pushed it. I had roughed it up a big before. Anyway I'm praying to the cannabis gods to not take what I have left. 8/23 Fucking pouring again. This sucks. I've gotten loads of advice and made another friend on here. I forgot my phone so I couldn't take pictures this morning. My spirits are up a little seeing that others are at least attempting to help. I'm headed to the grow shop after a night of research to grab supplies to battle this. I'll update later. EDIT: I picked up plant doctor at the grow shop. It was 50% off and I couldn't find anything with trichodermia. However, I've heard good things about this plant doctor. It's systemic and can be used as a root drench and a foliar spray. BIGGEST selling point for me is that it SPECIFICALLY lists fusarium, grey mold. Pythiym crown rot, black mold and all kinds of other shit. The thing that sucks is it's raining and it's not supposed to stop for a few days. That's going to make application more difficult. Oh well. I think I may do a root drench on the one plant that has a wilted bottom branch. I'll keep this updated. Thank you everyone who reached out. Especially growing grannies and my commercial buddy who is always here for me. However he has no experience with this so I'm kinda on my own here. EDIT: I couldn't find trichodermia and I don't have time to wait around and order. I found plant doctor which literally lists it treats all the possibly pathogens my issue could be. Even has a section for medical Marijuana. I did a root drench on the plant up front in the middle AND I did a foliar spray. Might as well get the septoria too. It's systemic but it gets in faster through the leaves I guess. It started sprinkling and I want to test this stuff out before I go ham with it. I did give some to the to other plants bit left my best AND THE TWO SMALLER ONES alone for now. I'm not seeing those issues on the NYCSA and I don't want to risk damaging it. I chose tge root drench as it's raining and the instructions for fusarium WAS a root drench. Thank you all for your help. I will close out tge question once I know it's figured out. Wish me luck. DID A SHORT VIDEO BUT WIFI IS SUPER SLOW SO I NEED TO WAIT TO UPLOAD IT. Went back over. Finished foliar spraying the other two and left the NYCSA and two Littles alone. Hopefully this works. I did I short video. Who knows if it uploads. UPDATE: Went back over and finished foliar spraying. Took a bunch of pictures and did a video but it didn't upload. I'm hoping this will do it. Plants actually look good. And they're flowering nicely! It's too bad I had to do a foliar bug this us supposed to combat PM and septoria as well. 8/24 It Rained last night but hasn't Rained today yet. It's supposed to and uts overcast. I'm really considering putting a roof on my grow (like rapacap suggested) for flower to decrease mold chances. Plants looked happy. I saw no negative effects from the Plant Doctor. I even sprayed a branch of the NYCSA and the stem and a little around tge roots. I finally feel like I can take a breath. I've been working so hard and worrying about losing g everything. I may have been able to save that 9lbkush but I don't think bit was worth taking the chance. The sun is peaking out now. My buddy at the grow shop called and set a side general hydroponics armor si 0-0-4 silica supplement cause it was 90% off. I pad like a buck sixty lol. I'll incorporate that next feed or water. Whatever comes first but it will be good to get it in the regimen. I was worried plant doctor might hurt but the girls seemed to kike it and I went ham on the worst plant. I mixed according to medical Marijuana guidelines on the label (Theres another label on the internet, it's not on this one, it's at the very bottom and just recommdations from commercial growers. I hope this stuff works. Things look better already though. That liquid kool bloom is the bees knees. That's making flowers pop up like crazy! I think I'll stick with it. I was going to use beastie bloom and cha ching later on (and still might) but I hate the lockout bullshit. I've done a bunch of videos but most don't get uploaded as i forget to upload when I leave and wifi is slow here. Anyway at least I've got a few good ones left and pleating the words of my commercial poll buddy, "barring anything catastrophic you should be fine. I know your anxiety gets the better of you sometimes." Couldn't be a truer statement. I'm still getting a tent and doing indoor though. I'm going to need to. 8/25 Did some slight defoliation. I think today I'm going to reorganize my grow space. Things are looking better though. Plants look healthier. Flower is on and they are going to beat hell. I'm glad I took a cutting from NY 9lb kush. I also took one from the NYCSA. THose are tge little ones. The 9lb kush is flowering pretty good. Too bad it's just on a 3 gal. The NYCSA us in a 10 gal grow bag though and is doing amazing. I still see septoria on the leaves. I'm sure I'll need to reapply plant doctor but thus far I'm impressed. Things LOOK better. I don't even remember the last time I watered. It Rained last night. Looks sunny today. I'm going to feed tomorrow. I want the soil to dry out though. We usually don't get consistent rain like this. It's a first for me. I'll update later if I get stuff done.still wondering if I should amputate that wilted branch or give it a bit. It's still attached right now. I'll get some sealant and do some more research.

Safe to say we're heading into flower. I'm pretty close to full strength on the nutrients at this point. Still defoliating and filling in the screen. Plant on the right is slightly behind as far as kicking into flower. Some yellowing browning just starting a tips. I'll change out the water tomorrow (on day 49). Averaging water changes every 12 days. Day 49: Did not change water today, will on day 52 or 53 instead. Decided it could just be the light being too close. Moved it up and did a little lst above the screen. All done removing branches and leaves. Great end to the first week of flower.

Apologies for not updating last week, I have just been really busy! These last couple of weeks have been great - her growth is coming along very well. There are no signs of any deficiencies as of yet, what is your opinion! In regards to defoliating and lollipopping - what growth would you suggest I get rid off?

LADIES AND GENTLEMEN, MASTERS AND BEGINNERS FARMERS! MY WORK WITH THIS SUMMER LEMON IS FINISHED. PLANT EASY TO GROW AND ENOUGH RESISTANT MAINLY IN SATIVA. HAPPY AND ABUNDANT HARVESTS FOR EVERYONE

July 24, 2020 The phenotypes have been stretching as normal. Some of them already passed the 30 in mark. Some bottom leaves are turning yellow but we think it is normal for lower leaves to die. We not only gave the plants Gaia green bloom amendments but also, we fertilized the plants with some Alaska morbloom 0-10-10. (Once every three weeks) Water intake has been increasing. Now the plants are being water every other day. 10-14 liters for 10 plants. Happy grow🤤🌱🌱🌱🌱!!!!

Welcome home, girls!

These ladies are developing very nicely, the left and middle one already started to bulk heavily over the course of the last week, while the one that got wind stress is trailing a little behind and will probably take a little longer. For the other two I would guesstimate that I can start flushing by the end of the week. The trichomes on the two are completely milky, however with no signal of amber yet

Hola a todos! Esta semana relice 2 riegos foliares una con aceite de neem para controlar unos trips que han aparecido y otro con un fertilizante organico MEN. Luego otro riego con PS. La planta de tierra la voy llevando para los costados para que no crezca para arriba, ya que de noche la luz de la calle llega a donde esta.

OK guys I was away for a week so this week we are at the end of week 4 veg instead of the beginning of the week. There was a boom growth period and the taller Punch 2 has bent herself to avoid getting burnt as she is 30cm tall, the other Punch 1 is 20cm tall and seems fine. I have just given them a watering with calmag and just a drop of PK ratio 13-14. I have also ramped up the lamp to 100% and put it at 55cm from the top of the plants. I'm hoping they will soon switch to flower guys fingers crossed. 🎄
