Megacrop 1 part works pretty well. I use it most of the time. I use promix organic or moisture control (Walmart). Watch ph as promix is peat based. Start at 1/4 strength… .25gpg grams per gallon and up the feed from there. I have never gone over 3.5gpg for autos. Photoperiod can handle the 6 gpg in flower. And welcome, don’t think I’ve seen you before… I joined in 2017, I see you were 2014. You could welcome me! lol!
