I asked you a few questions in response to your pm. I'll be happy to help out when I have that extra bit of info.
I haven't seen any major influence from the additives regarding ph being affected. I am also not using full dosages on any of them. Today H202 didn't affect my Ph at all.
Are we certain root rot caused Ph to become more acidic??
I see my batteries are dying in this new pen. Will check again tomorrow once I grab new bats and re calibrate.
Thanks a lot brother!
