I can't figure out what's wrong...I thought I had the problem fixed but it only made them look better for a day if someone has experience with this setup please let me know what I'm missing

aero 9 aeroponic setup...started in organic plugs and moved into the nets with hydroton pellets daily air temp is 75 when 400w hps light sun reflector is on I have a fan blowing in an opening of foil covered cardboard around the light which is 2 feet above plants I have a picture to show you what they look like this is during the middle of their day phase so I'm assuming the leaves should be atleast looking better than this...started with brita filtered water and added 400ppm of nuts are they too small could this possibly be too much food? maybe I should just run water through the system if that's the case. the plants used to feel almost leathery before some spots of yellowing have shown up but nothing this bad if this is running as a "TAG" is it possible I could be over feeding? over watering (didn't think you could wtih aero)? someone just help me I don't want to kill em

PS the bottom leaves on most are twisted and brittle and it seems to be traveling up to the top of the plant slowly if that helps oh and the water temp is hovering at 66 I read that the water temp is supposed to be very cool in aero someone let me know if this could be it possibly need it warmer till they get older then lower or what everything I read tells me to do something else
