You’re absolutely right that neither is needed as like you said most soils will buffer the pH with dolomite lime or some other soil conditioner and using tap water, where the pH is generally around 8, isn’t basic enough to affect the soil balance.  If you’re reusing your soil though I’d be checking pH as well as having it tested periodically to ensure there aren’t any excesses or deficiencies building up over time.

Humic and Fulvic acid are chealates and help plants by changing the electrical charge of minerals to make them easier to absorb.  They don’t really affect the pH of the soil by neutralizing acids or bases, although they do buffer the soil to make nutrients which are hard to absorb easier.  It makes a lot more sense if you understand cation exchange theory and how plants absorb nutrients, which this video explains much better then I could.
