chew on it.

The black tips are something else. I have seen this in Cattleyas where
the mature leaf starts to go black from the tip and the black stuff
slowly works it's way down the leaf until the leaf dies. I am told this
is caused by a fungus. I have not seen this in Phalaenopsis.

Don't know if this helps or not, but forget about crown rot.
