I've got a problem with one of my phalaenopsis I am not able to diagnose or treat myself. Recently, it developed brown and smaller black spots under its leaves, dark brown blotches on its stem and brown blotches filled with tiny brown spots on its blossoms .
The flower doesn't seem to be withering yet, but the disease seems to be spreading on the other stem as well. Just for safety, I lifted it away from the other phalaenopsis.
Could you please help me? I've searched the Internet and books, but found nothing like it.
