Hello! This is my first time posting, and my first time owning an orchid. It was a gift from a dad's friend and I've had it for a couple of months now. I recently moved it to a different spot and just today noticed these dark purple, limp spots on some of my orchids leaves. I'm afraid it might be something infectious but have also heard orchid leaves turn dark without sunlight. I don't have enough experience with orchids to tell myself but any help is appreciated! The first two photos are what I'm most concerned about. The others are spots that have been there for a while that I think might also have problems.
