Black marks on dracula

[vraev]

Hi guys,

I was wondering if anyone has faced this.

I have two dracula orchids growing in my highland tank: day temps...75-80F and night...55-65F. Humidity is sufficient as I have a mist king system and also a humidifier going for most of the day. I have highland nepenthes in the tank with thriving sphagnum moss. I noticed one of the orchids had scale on them..so I have been treating plants and getting it under control. But the other dracula doesn't have scale signs...but still has black marks on leaves. It grows alright... but old leaves get black marks on them. Clearly a fungus. But wanted to get a better idea.

here are pictures:
