Anyone make/mix their own fertilizer?
I'm going to be buying the separate macros and micros, traces (you add water, they're all powder) for my aquarium plants and would it make sense to just use the same stuff for non-aquatic plants as well? I think everything is there except for ammonia. I could mix it up ahead of time but I'd have to keep the macros and micros separate, I was told, due to chemical reaction. That phosphates react with one of the micro nutrients.
But if that's true, then how does Flora-Grow exist?
