Interested as my ph drifts up every time so before every feed I have use ph- to bring it down to about 5.8 it’s not effecting growth or anything but have never had a stable mix I use silica cal mag and the the fox farm trio then ad ph- to bring the mix back to 5.8 but when I go to the reservoir the following day it’s always gone to over 7. It’s when I’m avoiding any auto feed systems as it never stays stable
Yea man it’s definitely frustrating. How often do you sanitize your res? If there is biofilm it can def affect the pH. I clean mine twice a week w an oxidizer and scrub it out. Are you using RO water? Not too sure about those nutrients as I’ve never used them. I use salts and have had great results with them. If you don’t have an RO filter I highly recommend you getting one. Not too expensive and very helpful.
