Hi,
I bought this peace lily about a month ago from Lowes. I left it sit in it's container in this spot for about a week and then replanted it in a brand new container with regular potting soil (I think it's the MiracleGrow moisture control mix). The leaves promptly starting turning yellow so I started doing some research and have made some changes, but it's leaves are still turning yellow. I'm afraid it's just going to shrivel up on me and die (like so many have done in the past) and I really want this plant to do well so I thank you in advance for your help!!

The bay window it sits in faces south. The first picture shows about as much light as it gets. This is for a few hours in the morning and I thought this was maybe medium light, and then it's lower and more indirect light for the rest of the day. Since the first thing I read was that yellow leaves mean too much sun, I started closing the middle (the largest) window so it gets less. I've been watering it about once a week. Just the very top 1/4-1/2 inch feels slightly dry at that point (any lower is still pretty moist). I water it with regular tap (non-softened) that has been sitting out to let the chlorine evaporate. I give it a pretty good soak and then suck all the water out of the saucer at the bottom. I have also been misting it with softened water every few days. I live in Houston where it is usually pretty humid, but we've been running the heater non-stop lately. The leaves do not seem to be browning, at least not a lot, mostly just yellowing and they are still very pliable, not dry or crunchy. I cut them off when they are mostly yellow (and any browned flowers too) as close as I can get to the base.

I'm not sure what I'm doing wrong. Is this normal for this plant? It still looks good overall and even looks like there are some new leaves unfolding, but I'm afraid that's because I haven't had it that long. When I repotted it, the new pot is 2-3 inches larger than the original container, so did I go up in size too much? Should I try to repot it in a smaller pot? Or with different soil? Or am I watering too much? One other thing .. about a week after I got it, we went out of town for 2 days. I watered it right before we left, but I turned the heat off in the house while we were gone and it was cold that weekend. When we got home, it was really drooping. I watered it right away and it perked back up by the next day, but did I do some permanent damage?

Again, thank you soo much for your help!!
