    May seem like a simple question guys, but I have not had to do this before.
    My water supply is almost dead neutral at 7.2 pH. Seems to work ok for my conventional weed control products (maybe a touch high but the control is good so can't complain).

    However, I am going to apply some 1-2-3 NPP from ICT Organics to combat a fungal problem in a few resi lawns. Specified acidity of water to use with that product is 5.0-5.5 or slightly acid.

    How do I lower the pH of my water for these apps? Is it as simple as adding some household vinegar at a set amount to get the desired pH?
