Does anyone know what is causing the spots on my black cardinal philodendron? The older leaves have had them since I got the starter plant about 8 months ago. Finally getting new growth and today noticed the spots on the new growth as well. Not on all leaves and no pests I can see.
I think it may be edema. I was noticing this with mine so I repotted it… the roots needed more space I think, couldn’t take up water correctly. Since then the new growth hasn’t had those spots.

Looks like edema to me too. Too much water in the plant causing water blisters that pop.
