I am just about to start dosing macros and am wondering if plants are deriving any of the K+ in KNO3 or KH2PO4 or should I be dosing K+ from another source? Thanks, Jim

The plants will get K from both sources.You'll have to see how the uptake of NO3 and PO4 goes to determine if an additional source of K is necessary.

In my tanks I typically have to dose K (using K2SO4) at about 2X the ppm that I dose KN03, but I have high light tanks with a heavy fish loads.

Yes they do. My plants get their only source of K from those 2 mixtures.
