It looks like a lack of nutes or possible spider mites if you have a pocket microscope you will see them usually on the underside of leaves the eggs are little black specs if you see them

My first thoughts are a nutrient deficiency, although I wouldn't rule out pests either. But here is a link that lists both the Roles of Elements in Plant Growth, and symptoms of Nutrient Deficiencies. You can even download it in pdf and print it out, although the full document is 25 pages.
HS787/CV265: Fertilizer Management for Greenhouse Vegetables - Florida Greenhouse Vegetable Production Handbook, Vol 3 I would also email the pictures in this tread, as well as the other thread to general hydroponics, and/or the nutrient manufacture of the nutrients you are using, just to see what they think also.

I think it is probably spider mites, look for the little critters with a mag glass. Treat with pyrethrum, a mild insecticide, if desired.
