A lot of info being thrown at you.
I do not grow in soil, although I have been getting ready to do a side by side hydro and organic soil grow using the same nutes and clones off of the same mother, just to see the results. If I get real ambitious, I might add a coco pot to the mix just to see the differences.
IMHO, CQ is giving you some good info, but it might be a little overwhelming for a new grower. CQ's advice reveals the reality that most nutes lines out there are pretty much similar, especially for the "Grow" and "Bloom" nutes. As CQ said you can really make your own stuff for cheaper.
However, I think your biobizz stuff is just fine for your first grow. I am a real believer in adding enzymes and bacteria, but my lack of experience in soil keeps me from commenting on these. I would guess that some of these elements would be present in a good soil mixture, unlike hydro where we have to add everything to the solution.
My suggestion would be to go ahead and use your store bought nutes for your first grow or two to get a feel for your grow and how you need to adjust it for your lifestyle. Then, begin to experiment with concocting your own nutes if you wish.
