Hi all! New philodendron mom here. My Imperial Red had a couple yellow spots when I first got them, but leaves started yellowing, a new leaf curled very early on, and what was yellow but still smooth/flexible is now drying and getting crunchy. I’m new to plants in general, but this one was on sale from last year and in the winter. Any help as to what could be wrong would be great! It’s in a self watering pot which is something new, a couple weeks now which is also when I repotted. The too curled leaf is it’s newest and there is a new shoot in the back.
