Hi guys! Can anyone tell me what I’m doing wrong?? The leaves seem to be turning yellow and maybe getting splotchy. Also the ends are turning colors. She is indoor in a room with skylight ceiling (first 2 pics), so plenty of sunlight. I only water when the top soil gets dry. I have googled and maybe she’s upset about the tap water? I just want to make sure it doesn’t look like disease from the way the leaves look.
