You know I’ve never gone full hydro. It’s always intrigued me but never fully dove in. Maybe I should?

Yeah I hear that. When I first started messing with coco it blew my mind how it was supposed to be used. Can’t argue the results people get.

Straight coco is just latticing structure for the roots to spread out and occupy. It absorbs like a sponge and has some weird properties as to how it will absorb certain minerals and release others in their place. It's a hydroponic medium this way, but coco can also be used "like" soil, by throwing a couple extra things in like peat, perlite and some bioavailable nutrients like worm castings or compost so that you have microbe feeding potential. And what I consider an injustice to gardeners, these blends are put on store shelves and labeled as "potting soil" and they're not. If you treat it like one, that's how you get issues.

Yeah I never really like the cec of coco. I never really figured it out and I’m sure most of that had to do with me hand watering. With that being said I know a few people one being the owner of a large legal commercial facility right here in town that dries their coco back just like soil. Works beautifully. I do believe when you run coco that way you don’t get the full benefit of it but it sure does work.

I’ve gone down the organic living soil route a few times as well. If I remember right when I would use peat as my base to start amending with I would get good results but if I used coco things looked weird.

Plenty of folks here in the forums with experience to help you noodle it out. Not me though, never gone hydro either.

hey ninja , ive got some sulphur to lower my soil ph , ive put a dusting over my soil and covered it with soil and watered it ...but do you just do one application or should i dust 2-3 time through the grow ?
my soil ph is around 8, probably because i have some rabbit droppings in there .

A light top dress should give you a good 2-3 months of buffering so if you've got to throw some in, you should only need it once per grow.

I recall from 2010 similar problems caused by the coating of a pvc foil here in the netherlands, same yellowing appeared after 3-4 weeks.

Interesting theory and I would say if working the salt out of those pockets it's hiding in doesn't work, we may want to ask this grower if they're using an older tent that could have been from that batch they used bad PVC coating on, because it should remedy the problem we're seeing. Fascinating that growers themselves figured out the problem out themselves, disappointing it was never investigated to determine the root chemical that was actually poisoning the plants so that it doesn't inadvertently make its way into future products that will be used around cannabis.

No it was a certain black-white foil, same as oil in paints when heated by growlights they can cause fumes wich causes the same yellowing as i saw here in OT's photos they started after 3-4 weeks and will continue until it looks like a heavy PK burn.

Just tossing my 2 cents.
Moving to a clean growtent solved my problem.

It was not in the roots in was formaldehyde fumes with caused the plant not able to breath.

This guy used to grow in tents but has moved to a full room in the basement that he has split into 2 spaces.

Maybe natural gas or the likes in the basement? Op said air quality has been an issue for him personally.

Neither methane nor CO2 are harmful to plants. Nor is radon. CO, people would be long dead before the plants

I also had the after thought that he said he's had people out to test so they probably would've found something
