You should not see any difference. Cationic exchange resins work by replacing the Calcium with either sodium or in your case potassium to give a sodium or potassium carbonate salt. In our case, what is important is the concentration of carbonate ions present, as they act as "activators" for our developers. Since the concentration will remain the same as before you should see the same results.
