I'm not even trying to start shit with you. I find it seriously hard to believe that any good can come out of using sulfuric acid in a dilute or concentrate liquid. I can understand as much as what's left behind in pumice, like extremely small buffered amounts. But I can't understand pouring dilute sulfuric acid into a pot. The liquid would not be buffered near as well and I suspect it would be more direct and intense. Especially when you mean taking it straight from car batteries and diluting it. You should just amend a soil with a sulfurous mineral and nute/fert mix. Sulfur can be more easily overdone than phosphorus or nitrogen. I don't know why you wouldn't use something besides sulfur for pH down, and why you wouldn't use a more buffered form of sulfur like a soil amendment.
