Have you checked your Ph levels before feeding and then runoff PH? The same for PPM's/EC
This actually looks like something called black spot. I had it on an outdoor grow and its an outdoor problem. But with all things outdoor it could be introduced indoors. Have you brought anything in that has been outside? Pot, soil, really could be anything even you.
Is it spreading? How long has it been like this? And are there any other symptoms other than the spots?
Edit to make a point that this could be early phosphorus deficiency... check you nutrients make sure your giving the right amount etc.
Also what are you using for nutes?

Definitely not nute burn. Possibly calcium deficiency...
Also what substrate are you growing in?

I agree but normally calcium deficiency doesn't get to the leaf edges until most of the leaf is ate up, but yes it does look like some cal issue. Personally I use Raw Nutes with all their little ammendments, I'd hit mine with shot of phosphorus and cal/mag.

Yep will def need about 2-3 days, most likely 4 before you really see any changes. If no new issues, then I think the problem is solved. My plant took about 4 days with two doses of what I was using. I didnt use cal-mag because I am trying to go as organic as possible, but after 4 days she came out of it and is now back on track and not pushing out any calc def leaves...

That does look like possible LED light burn. The only way to tell for sure is it will start bleaching the bud or frying the hairs on them. Try adding the cal-mag like they said and if after a few days they're not changing and you're certain the pH is perfect, then it must be light burn.
