Avoid using any sodium based salts to adjust pH, they will negatively impact your soil, google sodic soils. Hydrated lime to raise pH (and add a little calcium), to lower pH nitric acid would be good if you can get it. Hydrochloric is OK but will increase the chloride

citric acid is supposed to be good for lowering

Nitric during plant growth, phosphoric during fruit growth phase

A hydroponics store will have what you need
