I'm not seeing any feed numbers on your diary? Looks like it may need some extra calmg, with that spotting but some of the other symptoms point to other things. Do one thing at a time. I'd choose calmg or a pk booster first. I'd also try and get that ph at a constant 6.5 for soil going in. Not as important if it has a stable microbial life. A lot easier to over water if it is truly soil, be careful when you flush them. If you do flush again and water comes out. measure its PH and EC, could give you a hint of what happening. high EC coming out means salt build up. Best Of Luck!
