the difference between gro microbes and bloom microbes is marketing. Sales..... As often happens, the salesman saw you coming and sold you everything he/she could.

I might accept " eat up the goo and turn it into moo" if you were growing organically, but you don't seem to know enough about microbes to even know what their for. That can not only be very expensive, but dangerous to your plants. Forget about microbes for now. If you want to learn about them, I'll post some articles on the subject and expect to do a lot of reading.
