How are you "sure"?
I'd like to know what levels of K+ consitutes an overdose or negative
effects on plants that is not caused by something else.
Erik and myself have done K+ levels with supposedly sensitive plants at
50-60ppm for myself, he went to 100ppm K+.
I've had high K+ for a decade now and cannot attribute a single issue to
Our plants are jamming.
Now do I need that much? No, 10ppm or more is fine and plenty.
KNO3 adds enough by itself.

If you are using KNO3, it's unlikely you need K2SO4.
