Could be fin rot starting. Test for ammonia and nitrites too, just to rule out spikes. Also, what filter are you using? If it's not strong enough, waste buildup could be the issue. My canister filter keeps things pristine.
Solid advice. Also, consider adding a UV sterilizer if it's bacterial. Worked for me when I had fin issues.

Thanks for the tips, everyone. Gonna test nitrates and ammonia tonight. Also ordered some pellets and almond leaves. Appreciate the help!
