Yeah it's one of the reasons I've been on the fence to do auto pots. You have to have a good root system before turning it on and I dont always have the biggest roots when I throw it in flower. When I over water and have too much light going they get like yours
Realistically the only way you can overwater in coco is if you have no perlite and lots of coco peat (coco dust fibers that are the size of coffee grounds). Many of us feed to runoff several times a day in coco. I think medidedicated feeds 12 times a day to runoff.
You spent half a day flushing the plants when they looked like shit. If the problem was overwatering, then they would have gotten worse after the flush instead of better. However, if the autopot was not functioning correctly and was pooling up water in the pots so that the roots were sitting in a pool of water, then that would cause it to be "overwatered."
Was it doing that? If so, then taking them out and doing a flush was getting them out of a pool of water and allowing the roots to get oxygen. Fully saturated coco will allow oxygen to get to the roots but coco sitting in a pool of water will not.
I’m starting to think the issue may have been the light intensity all along. At first, the plants looked like they were recovering, but when I checked again a few hours later, they seemed to go right back to how they were, even though the EC was where it should be. That’s when I started considering the light as a possible factor. I realized my PPFD readings were calibrated for a 3500K light, but I’m actually using a 3000K, and I’m not sure how much of a difference that makes. After lowering the intensity and rechecking, PPFD measured around 650, so it’s possible it was pushing 800 before. I’ve since dialed the light back significantly and it’s now in the 300–400 range. I’ll keep an eye on things to see if that helps.
Here's pics from a few hours ago.
Can you see a little taco'ing happening?
