I'd like some input at well. I want to experiment around. I've been using GH for about five years w/ great results... just recently started using organic suppliments and my babies are loving.. reacting very well to the organics. I'm going to have to stop using epson salts as I've read they interfere w/ some of those carbon based compounds. I'm thinking of going all oranic next grow. My local hydro shop guy praises Dutch Master. I wonder if the hype is justified............
