It sure looks like it-time to bust out the peroxide & maybe get another fan going in
there to keep the air moving.
1 part peroxide to 3 parts water(add a couple drops of mild dish soap to the mix-it makes the peroxide stick better),cut off the worse looking leaves and get them out of the room,
then spray once a day (twice a day wouldn't hurt) with the peroxide mix.
Make sure there's plenty of air circulation in there,especially after spraying...
Do you have pretty high humidity in there?
