if i was you i would just use the fish fert. for now. they look awsome they way they are going now. just wait till flowering starts, wich is usually early september where i am in N.E., and switch to your flowering fert. i try not to mess with what seems to be working. my plants pretty much get some organic compost made from grass clippings, leaves, and any other shit i trow in the pile the year before mixed into the hole before i transplant than one fertilizeing at about three weeks, and another two weeks into flowering and they always come out great for me.
