I’ve had her since 2022 and always water once a week (although may be late by a day or two sometimes). I have her right next to the window and she’s been in that spot for 2 years. Last week she started yellowing on one side almost entirely and I’m not sure why. The top leaves are still healthy and she has random healthy leaves a the bottom. Anyone experienced this before? Do I just wait until most of the leaves fall?
