Understood. I can see also why you like the Nitrate based N with soils like these to avoid Ammonium Toxicity with some sensitive plant species. My area I see an issue with the High Mg Clay soil, and Water onsite with High Alkalinity giving a "Liming Effect" from Ca Carbonates and Ca/Mg Bicarbonates from some of the really hard water sites. CA as well as Carbon/OM based products to buffer the anions driving pH up and buffer the sodium, and some soluble Ca helps to balance soil chemistry. Keeping a close eye with annual soil tests looking at Base Sat to help me adjust. Every season different with temp changes and moisture variations. I rarely have to aerate turf grass even my clay soils. Just balance them.
