well i'm gonna get the ph test tomorrow...but the plants look better than yesterday after the 1/4 of pro blend, think i may go with an 1/4 strength of pure blend and see what happens...its my 1st indoor grow and i'm totally lost...figure trial and error is also a good tool for learning...outside i've never really had problems but then again i wasn't using small containers w/ 24/7 lighting...thinking maybe an hour or two of darkness may help but i'd prefer to stay on the 24/7...any ideas?
