What do you use to bring the PH down? I am trying to find something better than vinegar (I grow in organic soil) tap water here is 8 out of the tap. I struggle to get it down to 6 using vinegar. GH PH down works, but not good for microbes. I have also tried a grow in the beginning using normal potting soil and it went terrible, had to amend the medium and add so much to it that buying some FF soil was a better option, haven't looked back since Sent from my SM-G955F using Tapatalk
