Ive done autos in both ocean and happy frog, although i did cut it a good bit with perlite. I only fed them twice. Once right when they started flower(about 4 weeks) and then after about another 4 weeks feed again. They didn’t get very big so mabie it was a mistake. Im not very skilled with them so take it for what its worth. Ive grown them outdoor only 4 summers. Never get much put of them but make for early harvest if you start them inside. I will dig up some pictures if youd like.
