I've been using PO4 to lower my wellwater from 7.9 ph to 6.8 ph. for about 6 years now. No issues during the growth phase, no issues in flowering. As with any additive or treatment, you have to learn how to properly use it.

To the OP:
The more you present yourself as a snot-nosed kid, the less likely you are to get any sound advise. This is a medical cannabis site, not a day care center, and punks get nowhere in here. As a matter of fact (in case you hadn't noticed...) they make a good target.
