Regardless of the dots, it looks like you're N toxic with foilage that dark. The dots could be an array of different things....kind of hard to tell.Does it looks like this? Only one leaf on my Bubblegum is showing this (so far). Only noticed it this morning. They're pale green spots. This is in week 1 on flowering. Plant has been healthy and happy so far until this morning.
Im growing under LEDS, ph of water is 6.2, using fox farm nutes at every other watering (using recommended dosages as recommended here: http://foxfarmfertilizer.com/images/pdf/FoxFarmFeeding_03-2015.pdf
Im guessing nutrient burn or maybe i splashed some water onto the leaves when i was watering last. Im keeping an eye on it.

And those dots are disturbingly similar to those of mites or thrips...gotta rule that out first.

I never realized that. After reading this: http://www.growweedeasy.com/nitrogen-toxicity-cannabis im gonna flush for about a week or two then start the nutes quite low. Thanks for the heads up man.
I inspected with a magnifying glass. They're definately pale green dots, only on this one leaf (which i've since cut away). Another part of the same leave had a brown stain.

And the underside of the leaves are clear of critters?..If the dots haven't gotten any worse so far, I wouldn't worry too much about them, but that's just my opinion...hope I could help some.

I've cut the leaf away. But the underside was clean. Spots were definitely pale green and not white. No bugs anywhere.And the underside of the leaves are clear of critters?..If the dots haven't gotten any worse so far, I wouldn't worry too much about them, but that's just my opinion...hope I could help some.

Ok well at least we have spider mites ruled out. Are you seeing anymore of the dots spreading?...If you're growing in soil I doubt it's a true Calmag def....but those symptoms do make me think of either water being on the leaves during lights on or some type of Macro deficiency, assuming the spots are spreading to other leaves....
