Hi all, This is a chartreuse form of philodendron (? Philodendron cordatum neon?) that I have been growing in an archway in our home. The arch gets very little direct sunlight so I have been supplementing it with a lamp. The leaves seem to be getting burned. Is this too much light? The lamp is not hot so it is not heat causing the problem. I have recently turned down the setting on the lamp ( it has three intensities, it is now at the lowest one.) The leaves are still quite chartreuse....I think they would be greener if the plant was not getting enough light. Or could it be a different issue? Like a problem with the watering? On second thought I do think it is the lamp because the brown spots are concentrated where the light falls most directly. The leaves further away are less chartreuse and have no brown spots. What's a girl to do?
