can vinegar be used if you run out of ph down

[latewood]

Hey all
I have a frend that works at a water treatment plant and we were talking about PH of hydro and soil.When he ask what I use to PH the water,and I said White Distilled Vinegar.He said excellent,but only white distilled vinegar and bakeing soda its more organic and nice to the plants.The guys 74 yrs
and 45yrs treating water.This one is cool has a phd and is high up in the brain dept.but dosen't like all the egg heads he went to school with,he sooner hang out with us poeple lower on the food chain.So if he said its ok I'll try it. Well thats my two cents. Peace

just adding for clarification...vinegar for ph down
baking soda for ph up.
