Best pH adjusting solution??

Hey I was just wondering what everyone thought was the best solution or powder to adjust pH up or down? I know people that have used Dyna-Gro up and down with good results. I personally use Hydro Organics Earth Juice natural up and down...Whats everybody's opinion, or what are y'all using?

What kind of medium are you growing in?

lol...that would help huh?? Right not using mix of FFOC and light warrior with added amendments....Next cycle am deff trying Nectar for the Gods soil #4 maybe with some Mass Whole super soil at bottom...think by next cycle I will be 100% el natural

EJ here too.

Ph up and down by gh.
