Raised White Spot on Phalaenopsis

[Marchminder]

Hey there OrchidBoard Community! Long time board follower, first time poster. I have a few plants I'm worrying myself over at the moment, the most obviously afflicted plant is a rescued Phal that had been doing well until recently. I don't know if it's heat stress, edema or anything else. I could be worrying myself sick over nothing but hopefully some wiser minds can spread some insight.

The other one I'm worried about is a Cattleya that I think is just suffereing from sunburn or heat stress. Right now these are relocated away from the rest of the plants.
