Virus, fungal infection, or slight sunburn on my phalaenopsis?
I have this phal, but ive noticed these top two leaves have a sort of splotchy pattern. The bottom two leaves have gone limp and slightly leathery. It was getting a lot of sun at one point. I moved it, but this is still continuing. Any thoughts on what this could be?
The first photo shows the part of the leaf shaded by leaf above is not affected. So that points to sunburn. Once there is sun damage, it can continue to progress. So might be a unsightly but it will continue to grow.
Also, when was it last potted? Phals get limp leaves when they are dehydrated - which can happen due to not watering often enough, but can also happen if roots are rotted by old medium so that they can't take up water. If you haven't repotted. Phals can be repotted at any time so take a look a the roots. And don't rush to cut bad roots, just clean off with fingers, don't remove old medium that doesn't fall off easily, and make sure it's help firmly in place in the new medium.
