Howdy redbud555,

I don't know much about hydro..but I'll try to help..are the bottom leaves the round leaves ? If so,then it's normal for the plant to shed those leaves. With the yellow spreading-it makes me think that the plants are having a nutrient up-take problem..or it could be that when the ferts kick in-you'll see the yellowing go away. Wait a couple more days to see how things work out.

Have a good one...Torog
