Dosing Dry Ferts
I'm using the GLA PPS-Pro fertilizers w/ Plantex, and the two 500ml dispensers. So there are two different mixes getting dosed daily, the Plantex in one bottle, and the other four dry ferts mixed in the second bottle.
I'd like to setup a dosing pump to add the fertilizers. Since I'm adding two different fertilizer mixes daily (the Plantex and the others) I initially assumed it would require either a dual dosing pump or two separate pumps. It occurred to me it might be okay to to mix both fertilizers (once in their liquid state) and just use one pump for both, lowering the cost and complexity of the setup.
Is it okay to mix the PPS fertilizers into a single liquid and dose that, or should they be kept separate and dosed separately?
