HCL + NaOH==> H2O+ NaCL. That is salt and won't be released. KOH ends is the KCl. Both end up with ionic chlorides nd are bad for plants.

H2SO4 +NaOH==> H2O +NaSO4. Probably less of an issue, but Sulfuric acid is really nasty stuff. Phosphoric Acid is far safer. Use of Phosphoric Acid also maintains organic certification. I can't say where you would be at with other acids.
