I'm with you, Kate. I like to 'rescue' the cheap ones at Lowe's that have finished blooming, and I've had some success with them, at least the first year. Now I have a collection of about 9 that are pretty finicky and not all that willing to bloom. I've moved them again this year so hopefully a bit more light will inspire them.
I had one that developed soft rot spots like that. I don't know if I 'cured' it or if it just healed up on its own, but I treated the spots with cinnamon powder, let the plant completely dry out for a week or two in a shady spot (good weather for that, right now - low humidity). and although the scars remained, the rot didn't progress. Still have that plant, scarred leaves and all.
Oops, sorry to spoil your 'exercise' for Kate there, Jim. "Your job, Mr. Phelps, should you choose to accept it . . "
Anyway, I was just wondering if they might not also be sun burn spots, originally? How much light is that orchid getting, Kate? Phals really do not do well with any direct sunlight, and the sun is getting stronger every day here. The leaves get lighter green like that when they are getting high levels of light. Those Phals with the purple leaf reverse usually have very dark green leaves.
