These are indoors right?

Is there a chance something could have splattered?

Edit: this is the only thing I could find and I'm not sure this is it but it might give you some place to start searching good luck

There's also something called black leaf spot but I don't think this is it I don't know what this is but I'm likely going to learn something on this thread I'm leaning towards some kind of a splatter if I had to guess

No, outdoors.

I have a bit of a system now for mites that worked on my photo period. I'll do the same with my autos.

Thanks for the sooty mold clue. I'm not entirely sure that's it though. I'll keep reading. I almost want to leave 1 leaf alone to see how or if this spreads out from the dots.

Can't think of anything that would have splashed the plants. I'm careful when watering and nothing else comes to mind.

Notice some leaf hopper damage in a few spots as well. Feels like the warmer it gets the more the bugs come out. Fun fun.

I'm really considering just taking the leaves off that have the dots. I don't want to take a chance on this spreading and it's farely sparse as is right now.
