Fox farms works fine, its cheap and works okay. Just use that and ocean forest with some extra aerating additives like perlite because it compacts after about 4-5 waterings so the roots don't spread so well. Make sure to look out though I got a batch of fox farms soil with gnats in it. I would look at something besides basic molasses since it doesn't really do the job a more synthesized nutrient with the same purpose molasses serves. Theres so many different nutes out there I wouldn't really say theres a best. I mean theres only so many ways to change NPK.
Personally I use Advanced Nutrients (no I'm not a fucking salesman) I just changed from soil to readygrow coco and AN and I must say I'm more than impressed. Of course I did drop the cash for it.
