In reply to your latest pics of your plants. I too am a hydro grower and use fox farm nutes. My plants looked similarly about a week ago and slowly got worse. This same thing happened during my first grow and I couldn't identify it. The second time it crept up on me, after much research I was prepared. A quarter of the nutes from the fox farm feed schedule is about the correct ppm for this stage of growth. The problem with using distilled water and fox farm is there is a lack of calcium. Most growers find this in their hard water, but unfortunately for us we have to use soft. I respect nongreenthumbs advice, i'm just giving you another less experienced opinion. My leaves began to contort and get dry, later spots began to show up on my leaves. I got a cal/mag supplement that has mg,fe,mn, and ca in it to help with lockout. First day the plants perked up and that "lush vegatative growth" promised by the FF came true.
not trying to scare you, just if you can't get it under control this may be your answer.
