First off...I've been using it for 3 grows now and its best to cut the dosage down to half on everything or risk burning some plants. I've never mixed them together myself but I understand it can be done. From the Go box, the Grow, the CaMg, the Bloom, and the other Bloom are the ones you'll use most. I use a 5 ml syringe per gallon of H20 but I only draw it to 2 and 1/2 after a few serious burns and a bad CaMg overload. Runs much better. It should be mentioned the soil is important too. I use FF OF which is hot to start with so...easy on the nutes especially early on.
