this is very unusual. Are the spots on the inside surface or the outside surface of the plexiglass lens? I imagine you tried wiping it using windex? Brillianize (by Kleenmaster) is another product that works great for cleaning plexiglass. I've typically seen water/residue spots that should come out easily when wiped. I would not use anything abrasive as this would reduce transparency.
Overall from what you're describing, if the spot don't show up in photos, I doubt there will be any appreciable reduction in light output. But if you're really concerned, send an email to support@californialightworks.com with a description and preferably a photo (try your best) and see what they say.

Sorry for the late reply. It took a long while for my post to show in this forum and in the meantime I got a hold of CLW support. The discoloration was indeed on the inside of the lens. I managed to get pics of it and sent them to CLW. They said it was from humidity and offered to clean it up once this grow was finished.
It's great that CLW has been so responsive (this is my second issue) and supportive, but I do think that this is an issue that can be corrected in future production.
