If there’s one thing I’ve learned over the years is there’s more than a few ways to grow in coco lol. I definitely feed stronger but not as much as I used to when starting out with coco/perlite. I don’t see any issue with the op’s runoff ec or it rising a bit, still very low imo. I think the flushing just made things worse, been there done that lol. Hard to know how much dryback he was getting, I can’t imagine much if he was feeding during lights off. The op will have to try different things and see what works for his situation.

Hey man, so I will offer my opinions here. Those pictures combined with what your feeding, those plants are starving. You have multiple deficiencies going on due to lack of nutrients. The light green and almost yellow leaves are a dead giveaway. Your barely feeding full grown plants what I feed my freshly planted clones. If your tap is .5ec and your feeding 1 ec your only suppling .5 ec of nutrition. Your going to significantly reduce your crop yield if you continue flowering with such low amounts of feed. The reason you didn’t see any improvement in the look of the plants is you started flushing and removing even more nutrients from the medium. If you had fed a stronger feed instead you would see a huge improvement in the appearance within 24hrs. Also there’s no need to be feeding in the dark cycle unless they are drying out completely. And I grew in coco petite mix for 7 years but now in straight coco for the last 5.
