need to see a close up picture..
Can't tell for sure, need a better close up. It could be edema which do to overwatering and will clear up, just back off watering it. It does look more whiteish than edema. You should do some google imaging to compare.

Do you have any drain holes in those cups?
That really doesn't look like edema to me, more like a virus.
Looks like a bad case of edema to me. Cut the plant back and dont water when its humid. It also looks like it should be potted up into a small pot
are those white patches removable? Do you own a hand lens or jewelers loupe? it looks like either powdery mildew or another fungus.

get that air circulating and dry it out, spray with h2o2 and neem oil and pray. Sulphur is also recommended to control....
I have a fan going. I took the plant outside cut the leaves off and have this one away from the others. Thanks for the help.
