from the pic you gave it looks like its heat stress, im not the best with diagnosing sick plants. hopefully somebody else can chime in with their opinion.

earlier you said you had foil in your rubbermaid, foil will make more hot spots than reflectivity. have you fed your plants anything besides water?
