My philodendron keeps curling its leaves and now is getting brown spots. I checked the roots and they seem okay and no pests were found. Any help would be appreciated. 6/6/2023. I repotted in an indoor potting mixture (it was all I had today). The main root seems white but I know the small roots are dark and thin. I am hoping this will help. It’s such a gorgeous plant and I hate that it looks so sad.
