Battery acid is hydrochloric acid. Don't use that. Hydrogen chloride is like bleach salts. Don't use strong acids or bases like that, they are below and above any range you need. You could dilute it, but I strongly feel that you don't want something that caustic in your pot or rez. Like, especially if you're busted, they'll bring in a meth cleanup squad.Sulfur does do well. Battery acid from auto zone is sulfuric acid.. It can be used as a ph down.
As I said, in organics, pH is much less important. With synthetics, you're using chelates (base elements bound to salts) which require a certain range for the bond to the salt to be broken by the rhizosphere. In organics, your microbes eat your organic matter and shit out what the roots can immediately take up. There's so much buffering that unless you're at 8.5 or 4.5, you should have no issue.
You just want a little natural sulfur or organically derived sulfates for terpene and resin production. Too much will be worse than applying too much nitrogen.
