In February I received this flamingo flower, and the underside of some leaves has v-shaped brown patches. Initially, I kept it under a high-intensity energy-saving light bulb, and was wondering if this could have scorched the leaves. I don't remember if it came this way or it got the patches after the light. I've since placed it in another room.
These photos were taken two months ago; since the plant is still alive and has sent up about two new leaves, I assume it's not life-threatening. The discoloration doesn't seem to have changed much. However, still out of curiosity, can anyone tell me what it's due to?
