Mine was stuck at a high PH for a while. Now after several doses (6 or so?) it is finally shifting to the PH it should be at.

It's my first hydro, so I think I messed up by adjusting the PH after adding the nutes. Am I correct in thinking this?
JaySin Reviewed by JaySin on . Does pH Down go bad? Like the question says...does it? I've put three full doses in my reservoir in the last three days. One dose *should* have dropped the pH by 0.5, but the combined total of all three has barely moved it 0.3. I'm using the exact same set-up I've used in the past, so I don't *think* anything's buffering the pH. Could be wrong of course hehe. Rating: 5
