This is something new, not sure if anyone can help. A couple of my plants are developing this. Ive noticed the little purple spots ages ago, but you never know what mottleing hoya leaves are going to have. However, it now seems to open up and has a parchment like semi transparent centre...quite dry. Ive treated it with all purpose fungicide..wondered if I should be looking for a specifical fungal component. I really dont think its sunburn, as they dont get any full sun.......but...I may be wrong. If it wasnt for the purple surround, I might have thought otherwise
