NPK solution from dry ferts

[illumnae]

Is it possible to mix up a stock NPK solution using KNO3 and KH2PO4, or will they react with each other?

Why did no one think about it ? I think it is a good idea. Less fuss. Anyway, there is a possibility that it will react with each other unless someone say otherwise.

Try that before for a while but then found that you will loss the ability to adjust PO4 level
