they vegged for almost 2 months. and you are right i did have a nute problem. the problem was that i ran out of the flora gro. so they were on just water for about 2 weeks, then i got my flora in the mail so i put it in. well i did not start with a small amount, i just put the full dose in in and it did not like it...it is all a learning process.. being a bubble head is harder than one thinks....
