If slightly raised, perhaps edema?

If so, due to cultural conditions. Coolish temps, (relatively) high humidity, and thoroughly moist potting mix (or soil).

Thank you. I did some reading on edema, and mine really doesn't look anything like what photos I could find. My room is around 64 (and I use heat mats) and more on the normal to dry side. The plants look perfectly normal until you look very, very closely. They still seem rather healthy and the undersides of the leaves are perfect.

Anyone have any idea about this, mine too have this problem. They seem otherwise healthy besides these black specks, very small. I'll attempt to add a picture in a little bit.

As a note, I'm letting them dry out and I keep a fan on them several hours a day. The temp is between 65-74 in the room.
