Fish/Kelp Fertilizer Crashing PH

The water from my well is currently reading 7.1-7.2 ph. I’ve been using Apple cider vinegar to drop the ph to 6.5. When I add my fish/kelp fertilizer to 1 gal., (no vinegar) the ph drops to 6.0. Is it necessary to get some PH Up to balance out at 6.5?

6.0 is acceptable.

Cool. I should say these are outdoor in soil plants.


Id bring it up a tad. 6 is just fine. But soil prefers it around 6.5.

When I add fish emul it drops to around 5… and i just adjust back up.

PH up on the way… Thanks!
