Burle Marx Philodendron going yellow
I inherited this Burle Marx Philodendron and it was very happy all summer. I stopped fertilizing one Sept and by Oct, it’s starting to look like maybe it has some sort of deficiency, because the leaves are turning yellow and fading very slowly from the inside out. (See photo.) Do philodendrons do this to make space for new leaves? Is it a nutrient deficiency? Is it unhappy with colder weather? Not sure. Any advice appreciated, thanks!
