Here is a write up about PH by the Iowa State University. Sulfur is going to be the cheapest way But peat moss might already be in your grow arsenal. https://hortnews.extension.iastate.edu/1994/4-6-1994/ph.htmlThis is for soil if you want to PH water Pretty sure citric acid is the cheapest PH down.

Earth Juice PH down

If you don't mind a little nitrogen, Alaska fish fertilizer (5-1-1) has a very low PH.
(Not suitable for hydro.)

Sulfur. Maybe some other stuff. Pine tea

I use 20% phosphoric acid. PH down. Get it for $10 a bottle at the hydro store.

molasses will drop your pH too.

I'm using Plagron Lemon Kick to lower my tap water from around 8.1 to about 7.5 and let the Biobizz stuff lower it more.
