Fox Farm is an Organic blend. So it provides nutrition. If you combine that with Coco Which is a soil-less or hudro style of medium; I believe you would be OK with Canna A + B. However; you would not need to add nutrients until several weeks into veg period. IMO.

I prefer Dutch Master Advanced which is closer to commercial grower solution than most nutrient lines. It can be used with soil or hydro. The only additive you might want to add to DM advanced is "Max". I have had great success with organic soil grows, right next to hydro grows and used Dutch Master Advanced A + B + Max. Good Luck
