I grow 60/40 peat/coco. I understand this is a different game because of how the different mediums hold oxygen, water and Nutrients. But at first glance , knowing you've been feeding them multiple times a day with runoff I would suggest letting the medium dry out for a day or two. Then start an every other day regiment.. I know in coco you need to keep it wet but fully saturated may be a stretch, as cannabis LOVES it's oxygen. Maybe try to lift the pot slightly!.. for reference , my plants this size drink 3/4 of a solo cup worth of water in 3 days. I let the medium dry fully and repeat until they're drinking it in 2 days then Transplant! See any DWC setup and learn that oxygen is King .. let it Dry before you Apply! This goes for my medium anyhow , and I hope it helps!
