^^^what he said!^^^
you want as little ph up/down, in your mix as possible. i don't even use ph up. i use pro-tekt for that.

I use the same stuff for up

My tap water is 7, looking to get down to 6. Just water for my mother plant that's in soil right now. How much PH down do I use per gallon? :) Rating: 5
