my water comes out of the tap at 9.8 iph it back to 6.8 but then I add my nutritions and my pH goes either way up or way down so do you pH balance your water after you nutrition it or before you nutritionsulfur be careful a little ata time.
Shots fired!!and what im saying is.. It doesn't sound like your meter is calibrated correctly... Doesn't matter if it's brand new if it isn't calibrated correctly.
And to answer your question about when should you check pH... Do you wipe before or after you take a dump?
