Thanks for the info...one more question. I'm using Ionic right now, and I know the have a hard nute version but, on this type I'm using right now its says target EC is 1.8. So that means like [email protected] for me. Does that sound right? Should I always keep it at 900PPM no matter what? Also, the only other additive I would be using is Ionic Boost during bloom cycle just to let you know.
