| Thank you all for the great comments! The spots are not growing perceptibly so I think they could be a result of some physical damage that was then exacerbated by something in its environment. We've got great airflow and I never let water sit on a leaf, but weather conditions in NYC are really varied from winter to summer: bone dry and low 50's to 1000000% humidity and 90's. Plus the amount of direct sun though East window changes by over 2 hours from winter to summer. But this phal has bloomed the longest by far of the 5 we have and seems happy—so I suppose I can find better things to worry about!
Thanks again everyone! This forum has been the source of my orchid education and I'm grateful for the info.
