I think we have the same thing going on bro. Tiny little insects hanging out on the outer part of the leaf, and my spots are looking pretty identical to yours.
I'm getting ready to check the plants here shortly for the first time today, hopefully I won't see a bunch like yesterday.
I hope you're able to get rid of them, they're a real pain for sure.
Other than the pests your plants looks super awesome as usual man :)
