i'm growing with FFOF soil and Two 40w Fluorescent tubes (for now) I also have a plastic bag with holes in the top covering the cup. When should i take it off? Anyway, i was just wondering if its normal for the sprout to have some strange discoloration. Basically the sprout has some grayish brown spots. thanks guys.
