nz ------ black spots shrivelled and dried out is considered good news.
Maintain dry leaves. The physan is a disinfectant - not systematic ---- so if bacterial or fungal activity is associated with the outside of the plant, then that can/could help to handle those organisms.
But for attacks going on both outside and inside the plant, systematic treatments should be considered ---- eg. monterery garden phos, copper spray, thiomyl and other treatments ----- if the pathogen (assuming there is one or some) is not identified ----- then it may take time to get a treatment (assuming there is one) to take care of the attacker.
It can be beneficial to encounter situations like this, so that you can then grab the knowledge that comes out of it. And eventually you come up with your own system - and will have minimal or even no issues with growing this kind of orchid.
NZ ---- I've never used physan before. But if you do, just use it on leaves and stem only. Not on roots. And maybe just use one application and monitor.
