It's definitely not heat stress with those temps (if they are measured at canopy)
I'm guessing it's a pH issue then... you can get pH test strips at a pet store in the fish section. They're much easier to test/read than a drip tester. My runoff is always colored anyway so the drip test doesn't even change the color of the water, it stays brown! Strips work fine though and they only cost like 3 bucks for a 25 pack.
