I have a Botanicare Turbo Garden that is a 25g rez with table. It's the ebb and flow version. I started with tomatoes from the greenhouse and cleaned and re-potted them in Sunleaves rocks. I flood the table 3 times during the day (lights on) and once at night. I'm using Fox Farm nutrients at the recommended rates (1600 ppm). I have fruit that is looking nice and appears to be growing (albeit very slowly) but the plants are starting to go limp. One of them is yellowing and has a mosaic looking pattern on the leaves. The light is a 400w MH Agrosun bulb on a 12 hour cycle. Any suggestions? I'm trying to do this as organically as possible. I realize that the Fox Farm nutes are not 100% organic.
