Thank you for the response! The affected leaves are all over, top, bottom, inner, and outer. They're not necessarily the ones facing the window, although I have been turning it every few weeks so it's possible the leaves are getting sunburned when facing the window and I just haven't paid that close attention.
I also forgot to mention that I found a white crusty substance on several of the leaves a couple of weeks ago. It didn't look like mealy bugs or any other pest I've seen before. I didn't treat it with anything but have been keeping an eye for any more. See the pic below. Any idea what that is?
