The water alone has 8.1 PH but after I put nutrients it drops to 5.8-5.9

I use two pH meters one reads 5.4 and the other reads 5.8-5.9 I don’t know which one is correct

What brands are they and when were they calibrated? (If not calibrated, purchased?)

maybe neither? What's the EC or ppm? Those small plants don't drink much, so as the water evaporates the medium might be too hot. When you water those make sure you get a good amount of runoff if you're in coco.

500 ppm

One is Apera and the other is Bluelab

Regardless of the brand, a pH meter will need to be calibrated periodically. Apera uses 4.0 and 7.0 for a 2-point calibration.
Bluelab I think calibrates to 7.0, but check manual, it's been a while.

What is your feeding schedule?
Do you always feed to run off?
Do you ever use plain water?

500ppm is pretty light, but the medium could have salts built up in it.. I’d check the runoff ppm just to see.

I second the PH drops.

Never wrong, no calibration needed.

Great advice if the OP wasn't in coco.
My Bluelab uses, 4, 7 and an optional 10.

I use it every feed, before adding PH up and retesting til it's 6-7, the test water is bright red

Are you saying it's bright red after you adjust the pH?
