What you plan to purchase is fine; you can leave out the iron chelate.

You may want potassium sulfate just in case you are finding you have a potassium deficiency, but there shouldn't be one if you are following EI (potassium is contributed from both the KNO3, KH2PO4, as well as the K2SO4 that is already in the GH booster).
