Totally not worth it unless you're a super chemist. I buy my nutrients and it makes more sense to me. Let someone else do the mixing. I use Advanced Nutrients, but not their organics. They have some, but I've found the regular nutrients to be even more effective for growing super MMJ.does anyone here make there own organic nutrients? I did some reading and learned egg shells wood ash, coffee beans and some other things give the same nutrients the fox farm and nirvana tea give. just wondering has anyone tried their own nutrients and how did it work out
