Hello, I have been having some issues with two cat palms in two different locations in the house. One is at a sliding glass door and gets plenty of light, the other is in a corner next to a window and gets about 33% the light, perhaps. They both end up yellowing more than I'd like, particularly the one with less light, and the palm getting more light develops a sticky oil film. I've adjusted the watering schedules to make changes with moderate affect, so I sense there is a larger adjustment needed. Thank you!
