What do I have going on here?

This is on one of the plants, don't see it on the others.

My first guess is that you got Bugs.

My first guess is a Calcium deficiency.

Bugs! Could be chinch bugs. Mostly cosmetic damage but an infestation can do some real damage.

Looks like lace bugs to me.

Howdy Donnies58, What are the growing conditions? Indoors, outdoors, growing media, etc.? the black spots look like what we called 'fly spots' (house fly poop!). Have You seen any critters of any kind around?

Hope it's not black spot disease...kinda looks like it. 😟.

Growing inside in a combination of Happy Frog & coco coir. No flies in the house. However I did have to leave all the plants outside for a couple of days a few months back. I have ants inside but they avoid the closet. It's only on this one plant & I did spot maybe a little on one of the others. Funny thing is I have 3, two of them are the same whatever strain it is & the other one is obviously different & is not affected. I have ordered some stuff for bugs, just in case. Also thinned out the two plants some & removed some of the leaves. It seems to be mostly on the bottom leaves of the plants. Middle, upper part is fine.
