Changed the nutes Saturday. Once the nutrients were mixed in, pH 7.0.
It took 60 milliliters of phosphoric acid to lower the pH to 5.5.
30 hours later PH was 6.6. added another 15 ml phosphoric acid at 11:00 p.m. on Sunday night.
So far Monday 6:00 a.m. and 6:00 p.m. pH 6.2... dare I to hope that it has stabilized?

Thank you for your help.

No problem brother… when you initially mix a new res… give it a few hrs then re adjust the ph again. After that it should be stable. If not let me know ans we can tweak things to get it perfect

I have, and it is always a possibility, but I'd rather just use tap water if I can get away with it. I acquired phosphoric acid yesterday and I am changing the nutes this morning . I'll make sure I flush the system real well to get all the old solution out so I can start fresh.
If I can't stabilize the pH with phosphoric acid, I will dig into learning about buffering.
If I go with RO, wouldn't I need to add a buffer to that because of the low alkalinity?

Yeah you would need to add but it’s cheap and easy to do.
