Maybe I’m crazy but do you have a humidifier going with hard water ? It looks like your pre filter to your carbon filter in the back has hard water build up or powdery mildew build up? Hard to tell but if that’s the case your Prolly not getting the best air flow. But then again just what I think I’m seeing. Not saying that’s your issue but should prolly be addressed.

Well done for getting them this far on your first grow! Not long to go. Worth tagging a few of the experienced lads and getting a few opinions @Waira @archie gemmill ...Im sure there plenty other lads on here aswell. Im not familiar with your nutes and soil etc but i had a similar issue at the same stage...I cant say i solved it but i ended up feeding calmag...epsom salts...extra nutes...less nutes....and in the end it just got worse...I suspected a nute lockout as they wernt responding to anything...so even at that late stage i decided to flush the soil with lots of fresh water and basically start again!...luckily it paid off for me as the plants responded quickly to the normal grow and bloom nutes and starting sucking up water quickly again. Im not saying for you to flush! It worked for me, your issue may be a simple one. Hope it goes well. Im sure they will be fine.

is it sitting in a bucket of dry ice ?
great job getting this far,you nearly done i aint really quailified for the infirmary if it aint biobizz soil n nutes.as im an eejit il give my 2cents.an opinion or collection of thoughts,not a diagnosis :smoking:
half soil half coco....soil likes a higher ph than coco.coco likes lots of calmag every feeding,never plain water....so to me thats a conflict of 2 mediums in same pot.
buds look good 2-3 ish weeks left.
could the kind soil nutes be depleted ? maybe a bit soon for natural fading.
please wait for a sensible person to come along
good luck n keep er lit

Since the soil says 6.3 to 7.0 and coco is 5.5-6.2 and you went half and half what are you phing your water? Are you feeding cal mag since using leds. And how much?

Hey now! Thanks everyone for the complements on my first grow. We started with three and now there is the only one standing. Learned a lot through this experience, and will definitely be doing things differently next run. To address everyone's question above


Was using hard water for humidfier during run. So you may be correct on your observation. I was struggling with airflow this run at one point the tent was getting very hot 86ish. However I was able to correctly install the inline fan and was able to fix this issue. Hopefully this isnt a powder mildew experience. @EPDMGUY

Not sitting on a bucket of dry ice. on kind soil website they say you just use a 2nd medium, preferably coco loco. As kind soil is too hot just for the plant and will kill it. Perhaps the nutrients in the kind soil has been used all up?? As you said @archie gemmill

The owner of kind soil said never to use any cal mag at all, or any supplements for that matter. All had to do was make sure the ph of the water was between 6.3- 7.0. @Boognelson87

Now they did say Water only pretty religiously. No other supplements. But from what I seen with other growers they all never had an issues with using recharge and mammoth p with kind soil.

I did stop testing ph of the distilled water bc the brand was pretty consistent everytime I bought it. Had to be between 6.3-7.0 which it always was.

I'm just trying to get this girl home. Hopefully she can make it another few weeks

Here's some information about kind soil for anyone interested or curious about their water only soil.

 

[Boognelson87]

So what are you phing to using the loco base medium? I know companies say things but to be honest.when running leds i think you need additional cal mag. have you did a google search or afn search to see similar rwsults? Im sure a few use kind soil. I still dind it odd they say its ok with 7.0 ph with coco base.

thats What I thought it was is hard water. Take your pre filter and clean it ASAP you are most likely over working your fan if it is clogged with hard water. I only know because I had the exact same problem in the beginning of my grow! I checked my exhaust vent one day and fan was on high and air was barely coming out, didn’t know what the hell was going on I took the prefilter off and the dust from the hard water was so bad I couldn’t stop coughing and my fan started blowing again like a champ. Cleaned it and it was back to normal. Make sure if you take it off don’t bang out al the dusty hard water build up in your house it makes a mess and it stinks a little.

You were spot on my good sir. You honestly just solved a major riddle I was trying to figure out during this whole damn grow. This issue was driving me bat shit crazy lol. couldn't figure out why I was getting poor air circulation with my inline fan. I'm growing in a 3x3 with a 6" inline fan I shouldn't have had any issues.

You're the fuckin man. Just removed my prefilter. It was fucking covered in white chalky dust. I removed my plant while I was doing this. Hope this shit didnt cause major damage to my girl.


Jeez I'm such a bone head. Didnt think twice about using hard water for the humfider.
