I love ur signature on your messaging!.... The first thing i would buy and personally couldn't live without is Super Plant Tonic. Unbelievable for roots but has all kinds of goodies for entire plant. Second, i would get the Grow It Green. Again its loaded with organic goodies and has a higher n-p-k- rating. One of the good things about BMO is that u dont have to run a typical NPK value system. It hs 65 trace elements and very efficiant microorganisms to make the best out the NPK they are recieving, and of course thats where the trace elements come in. I feed Backstrap mollasses, along with BMO line up. My schedule is feed one week, water the next. Works great for me. Its hard to nute burn with this stuff as well. It just flat out works and works great and happens to be a third of the price of lesser nutrients. Great idea on purchasing the guanos because at times you will need to up your nitro, and adding phosporus during flowering will just make your buds denser. Another reason I feed backstrap molasses. It feeds the microorganisms which in turn feed my roots which in turn allows the BMO goodness to make its way to my buds. Simple theory but simply works. And if have the 35$ I would recommend buying the entire package. they work so well with each other, and its so cheap its kinda hard not to. But I do know money's tight . Anyways, good luck bro
