Default Paphiopedilum cross seedling diseases

Hi
I have these Paph cross seedlings grown from flask. They are about two year old now. Suddenly the leaves started developing blackening and burning symptoms from the tip of the leaf and spreading to the entire leaf. I have attached the pictures. Any one can throw light on the disease and the treatment? Thank you in anticipation

Just a guess, but it looks like anthracnose.

I would try treating with a copper-based treatment.

What are your growing conditions? They look very wet.

Northeast of India, I would guess, is very humid and hot. Probably rains a lot, also.

Hi
Thank you for the response, to begin with let me try a copper compound and see how it responds. Further the seedlings are in Green House and there is no excess water from rains. Presently I am in Bangalore, Southern Part of India, where humidity is not high. The wetness appearing is due to the watering done in the morning before taking the picture. Thanks everyone
