Quadgrow Q

[Mitzi]

I think if you mix the two solutions before they are fully diluted then the chemicals in them can react to form salts or some kind of compound which "locks up" the nutrients so the plants can't access them. However, I don't really understand why you have to mix them at all. Why not feed A at one feeding and B at the next?

You could do that ... but means 50% of nutrients missing at each feed
