Had black spot leaf mold once, it looked very similar, beyond that I draw a blank from my past experiences...:

Will it wash off? Pics are too out of focus for me to see up close.
Looks like you spilled or sprayed black molasses(HI BRIX) or a tea and could have stained the leaves.
That's all I got.
Do you think it's a black mold of some kind?
Try a small amount of soapy water and put a paper towel down or something to divert the water away from your soil medium.
