I can't claim to be an expert in soil chemistry dynamics but I let you
know what I know second hand. Thanks to the buffering capacity of your
soil or potting media the pH of you water in itself is not a problem if
the alkalinity of that water is low.  Alkalinity of water refers to its
buffering capacity.  So if your water alkalinity is low the buffering
capacity of your potting media and the acidity of the fertilizer you use
should neutralize any effect the pH of your water may have.
