I want some help with four of my Phal's that seem to have gotten some kind of illness from ????? I don't know what it is. It seems to cause the affected leaves to become deformed as you can see from Pic 1. It starts out as a lime-green "watery looking" circular lesion, then yellows with a dark center and extends as you can see in the remaining pics. So what is it?????!!!!!!! If anyone knows....thanks. I have placed the affected plants off to the side away from the others in the GH.
