sunburn?
 

Hello again

I will post some photos of one orchid with specific signs that I think is sunburn because it's been really hoy the last few months, I just want to be sure so not to be worry for anything else. in general the orchid looks good

Thanks!!

Yes, it looks like sunburn, but I have to wonder why that is not burning from the top, down.

I agree with your assessment, Ray. But remember, not everyone grows in a greenhouse. As a windowsill grower this is exactly what I would expect sunburn to look like (one sided and not necessarily from the top down).
