Im using cutting edge solutions currently, I was going to use fox farms and my local grow shop suggested that brand as it is cheaper. So far I can't complain about the nutes, im sure there is better but its easy to use and the buds have been dense n frosty. I use the base 3 along with plant amp n mag as well as sugaree n sourdee once I hit flower. If ya using happy frog soil I wouldn't use nutes till bout week 3 or 4 or once it flowers. I over fed a few too early n locked em up.
