I noticed some black spots on a couple of my plants. One has holes in the edge and a few black spots. I checked for creatures and didn't see any. I have sprayed them a couple times with epsom salts and noticed it leaves some residue in spots. I wonder if spraying them and then putting them under lights, if the water droplets didn't actually act like a magnifying glass and burn them a bit? That's the first thing that came to mind. I did some searching here and found some problems people were having with bacteria. I hope it isn't that.
I guess I may know in a couple days if this spot develops into a hole or grows.
