ok so I changed my system out, took 3 full bins of RO, did 2 together and then ad to add another because it wasn't enough! I set each bin at 0.2EC cal-mag and GH nutes 3-2-1 to a full EC of 0.85, pumped my system out and the new in and already about an hour later I can see a difference! they were growing before but nothing like they should have been! it seems that the 0.2EC is needed with RO and people saying that you don't need it are wrong!
