I have a sick phalanopsis. I have been keeping it in a screened in
porch in S. Florida and watering every few days. I cut one of the top
leaves (probably a stupid thing to do) as it seemed that the leaf was
deteriorating and I thought it would spread. Now I see black spots
inside the leaf. Looks like it could be a mold / fungus. I'd
greatly appreciate anyone's thoughts on what it is and how I can fix
it.
