Skip the KH2PO4 and test the phosphates in the tank right before a water change. If there is still a positive test (no matter how low) then the plants are getting enough phosphorus from the water change.

If the plants have used up all the phosphorus you might think about a low dose just once a week, a couple of days before the water change just so the plants do not run out in those last few days.
