White blotches on my phalaenopsis leaf
I wonder if anyone can help me, I have an otherwise healthy phalaenopsis plant which has two fairly large white blotches on one leaf, they have a black ring around each white blotch. Its almost as though the leaf has bleached.
I am not sure if the leaf has a fungus or virus problem or whether it has been bent against the ceramic tile. The plant sits on my kitchen window sill with five other plants which are unaffected.
Any thoughts people ? I have had a quick look through the site but can not see any plant that looks similar.
The photos are of the front and back of the leaf.
Many thanks
Carol
