Welcome ! I would start by verifying my pH meter in a clean fresh bottle of 7ph solution .And if pH run off is 7.2 PH I would focus on trying to get it down to around 6.5 PH . The couple single leaves on the bottom looking beat up they’re going to die and fall off anyway.
It’s hard to see what’s going on in the pics, but pH of 7.3 is far too high for soil. You should be aiming at pH 6.2-6.8, with 6.5 being the sweet spot.
Also, if you’re using one of those inexpensive prong probes to measure pH, it’s not accurate enough. They usually read pH 7-ish no matter what.
