Jane,
The spots may not have been caused by the same reason. In the lower
photo these white spots on top look like they have been there for at
least a while. They will remain on the leaf, no wiping them off. The
one spot seems to have a trail off the edge of the leaf. The plant has
grown on with a small indent at the edge. It could have just been an
inadvertent injury or scratch.
One thing to consider is that the orchid was visited by a slug. The
underside may have marks where the lil pest was munching? If there are
slugs hiding down in the media during the day, you can just set the
pot in water that covers all of the media. In about 15-30 minutes they
will at the top of the plant waiting for a helicopter to save them
from the flood! If it turns out be slugs you can use a product with
iron phosphate (such as Slug and Snail Bait distributed by Lilly
Miller Brands) to spread around the growing area.
Regards,
