You do realize that EI is a specific fertilization scheme with substances in different ratios than PPS-Pro right?
EI is not a scheme of dosing ANY fertilizer. It is a scheme for dosing the specific fertilizers specified by the recipe. PPS-Pro contains other compounds as well. You can easily unbalance the aquarium by dosing PPS-Pro per EI.
My two cents.
