IMO it'll work as long as you don't include any fert with iron in it. I can't remember if it is potassium or phosphate, but one of the two doesn't mix well with it. Now in your diluted concentrations, it might work. But I guarantee you that if you take normal strength ferts, and mix them with something with iron like Seachem Iron, or TMG, you'll get precipitates.
So for me, that means I can only dose macros. I use TMG for micros, it has iron, so I have to dose that separately. I need that 2nd pump!
So, I guess you need to be careful in the same regard. Only problem is, in that water volume, a precipitate would be really hard to see. But at the same time, at that level of dilution, maybe it would work just fine.
Who's to say. Any chemists in the house?
