Soil meters are 100% unreliable crap. Unless you are either replenishing used soil and looking for a ballpark figure, or if you are mixing your own. Most quality potting mixes are pre-buffered, so will show no changes till buffers fade. You'll want to keep your water from fighting the buffers, and only knowing soil ph won't help there.
overwatering makes leafs droopy, pH causes nute lockout and can show as different symptoms. Drooping leafs with yellow banding could be zinc, but as I said, prolly a result of pH being off.

I don't think it's overwatering because a 50/50 mix of peat and perlite is impossible to overwater if he's waiting for it to dry out, which he stated he was.

I'm not suggesting a soil meter, but a complete soil test like LaMotte or Security. This will tell you the pH of the soil, you need a 2nd test kit that measures water pH so you know what pH you're watering with. It also doesn't hurt to know (yes, in "ballpark" terms) if your soil nutes are balanced. I've suggested soil testing to many people who find they have way too much or too little of one major nutrient, or their pH was off.
