Dying leaves

Question

I bought this philodendron selloum about a week ago. It was outdoors at the store but I have seen people keep them indoors. I put mine inside near a west facing window by my other philodendron which seems to be thriving. It had just been watered when I bought it a few days before but I was going away for the next three days so I thought I should water before I left. When I got home, I noticed three of the leaves had turned yellow so I cut them off. Over the next couple of days, a few more leaves have turned yellow. Is it not getting enough light/too much light? Did I over water it? Should I re pot it? The roots are showing and I read online that you should re pot them when the roots become visible.
Any advice would be so appreciated and helpful!

This is the window it sits by.

Is it too low?

I cleaned the leaves with 2% milk when I brought it home, do that hurt it?

Should I fertilize it? And what should I use?

Thank you!

Answer 1

Yellowing leaves can be watering issues, or changes in growing conditions.
