Beginner Gardening: Peace Lily blooms folding backwards, 0 by SemiGreenThumb

Okay so I moved my peace lily to a new location because it was in the path of one of my AC vents and I spray it daily to keep up the humidity. I also cut back on watering to see if that would help with the yellowing leaves.

The Good News: A new bloom opened up a few days ago and shown no signs of folding backwards.

The bad news: One of the older blooms is turning brown and looks like its dying. I don't know if this is normal or if its dying because of something I'm doing wrong.

The other bad news: The tips of most of the leaves are turning brown. I'm guessing this is a watering issue, but I don't know what to do.

I read that peace lilies start to droop when they are ready for another watering so instead of watering every three days like I was doing, I decided to cut back until I noticed some "drooping". After like a week I noticed no drooping and when I felt the soil it was pretty dry, which I heard was a big no-no for peace lilies, so I watered it. I still tried to wait until it drooped for my next watering, but again a week went by and the soil was dry with no drooping, so I watered it. I can't get a good watering schedule because I don't notice any drooping before the topsoil gets dry. Am I not waiting long enough, causing overwatering? Or is the drooping so slight that it's hard to notice?

Help please...
