Discoloration/Downward Clawing... Help!

Greetings! I've been updating my issues in my grow journal, but am now calling out for help because I'm at a loss and the issues have not gone away.


I have 2 plants in RDWC and only one is showing these issues, the other one seems fine.

Using GH trio + calmag + hydroguard.
Light schedule is 18/6.
Chiller is set to 65 which keeps the plant sites around 67-68.
Temps are in the low 70's with RH in the mid 50's.

Also what is the pH?
Have you checked under the plant's leaves with a magnifying glass?

If you look at the grow journal pic I've been recording the PH and other stuff there, I originally had it a little high in the 5.9-6.1 range but I've been trying to keep it at 5.7-5.8 now.

I haven't used a magnifying glass but I've been trying to carefully look closely at the leaves and I haven't seen any bugs or anything.

Edit: I re-calibrated my PH sensor again and the PH went from 5.7 to 5.5... I wonder if that was the problem. I haven't recalibrated it in about a week and a half.
