Hey all, I am just in the beginning stages of starting to do my first hydro grow. Just a question about which nutrients to use: I know that GH is the number one recommended line to use, but how about the General Organics. Is it ok to use this in a hydro system? Just in the little bit of research ive been doing, cant seem to find out much. Everyone seems to only use it for dirt, just want to know if its safe to use for hydro? Any info is appreciated, thanks.
