Tbh...um feeding currently at ph5.2 ec1.2 and I'm seeing no further deterioration. I know the ph sounds whacked...but if it's working I thinks she's liking it. Growth wise it's not as I'd expect it to be but will keep you'll updated..time will tell..

You won't listen to me but you need to stop feeding at 5.2. It's not low enough to kill her (yet) it's low enough to lock many nutrients out. Which is why she's doing better. But please feel free to correct me again.

Wait, didn't you just say this?

Yes I did and your previous responses sounded like you knew better hence I asked. But going through the thread, youve asked me to maintain ph6 and reduce ec. I was wrong earlier on the ec being 1200 and it actually is ec1.2 or 600ppm.
Any thoughts regarding flushing and the inflow ec of the flush?

I'd mix up a batch of nutrients at 6.0 pH and .8 EC and run a ton of that through the coco. Despite you saying your runoff doesn't reach the bottoms of the pots they should still be elevated. Hard to believe you are getting enough runoff and those saucers aren't overflowing... I'd also drop your temps lower, that's pretty warm.

I'd then continue to feed the same solution for a while until they recover and get larger.

Why do you keep flushing your substrate? You can't flush the plant but you can set up an osmolar diuresis using high EC where it leaches liquid from her.

I'd be feeding her at 200 - 300 PPM so .4 -.6 EC on your meter. I'd then pH your water with the nutrients to 5.8-6.1. I have reservoirs I mix once a week. I add nutrients then pH down to 5.5 and wait over night for the carbonates to blow off and it leaves me at 5.8. My reservoirs usually float up to 6.0 or 6.1 over the week. That is how I do it. It's not how you have to do it

I'd also soak the medium she's in. I understand you're in airpots and there's an internal gap so her feet aren't wet so you don't have to worry about her sitting in water in her saucer.

Thank you for replying.
My pot is 9 litres. I've been feeding 1litre of nute solution and getting a runoff of 350-400ml.

Thank you too for replying.
Regarding feeding @ 200-300ppm, for how long do you recommend? I like the idea of osmolar diuresis..
Also, I adjust the ph of my res the same way as you do.....been growing successfully in dwc for the last 6 years until a serious case of pythium set in and changing things didn't help but coco seems more forgiving..

I started this journey in NFT rails. Coco does seem easier in some ways.

I see what @twentyeight.threefive posted about 400 (.8 EC) is probably good. You just want to be consistent and low until she looks better (more consistent coloring and less leaf twisting). Hydro turns around fast, so days to a week. If she's looking good when you mix your next reservoir up her a little.

Your plant doesn't look bad. I'm guessing your big issue has been a lot of flushing and low pH.

get some mega crop or jacks- stop feeding dude- stop watering step back breath and do as BK said easy fix .... stop trying to complicate things by over thinking - thread is going in circles

Just what you need, another opinion :). Consider swapping to GH floratrio temporarily, ph 5.8-6.1, maybe 400-600 ppm. Just to make sure they're getting all the micros needed. Someone mentioned that maxigro may not have all of the micros. Just a thought and I think the trio is still fairly inexpensive.
