It says you're giving 37 ml/gal of nutrients, I'm not sure exactly what you're giving but 37 ml/gal of anything seems way to much.
Your leaves are dark green, curling, and plastic looking so at the very least you probably have a nitrogen toxicity but without knowing the exact products you're feeding with, could be other toxicity going on.
I would water with plain water, no nutes and see if conditions improve. When you start feeding again, start at lower doses.
