White/yellow spots - Need help please

Hey guys growing OG kush this year. About 3 months old now. Feed DNF 2 part formula every 3rd watering. Also add in grass clippings and banana peels lots of them. Promix and triple mix soil mix. In full sun.

In the past week these spots have popped up on every plant the biggest girl first. I have no idea what they could be and have found very little information. Have no visual sings of any pests at all. After I moved them to a area in the bush for a week or so with little light it seems like it began then. They are now in full sun. Any help is appreciated. Not sure on PH of soil. Thanks Cheers.

looks like bug damage, check the under side of the leaves

No bugs are visible. No webs. I swear it happened almost instantly after feeding one girl yesterday. Didn't see any signs on her, fed, went back maybe half hour later and she had spots too. Maybe I didn't see them before hand not 100%.

I'm not sure on the bugs being the cause, after a week the spots will turn yellow and leaf will become burnt looking. Still haven't found much on it.

thanks for all your advice.

That's definitely bug damage Idk what they're called but they're green and reddish and kind of resemble leaf hoppers. I'm dealing with them right now in my guerilla patches. Damage seems mostly cosmetic so far..

Ya mine have the same thing. Can't see no bugs at all. I think its a calcium deficiency. I'm trying some cal-mag today.hopefully it works...

Google "leaf hopper damage cannabis" and I think you'll fin

100% positive on that... they don't seem to like direct sunlight so they can be hard to find

alot of critters do there damage after dark
the shape of the dots seem to regular (round)to be a calcium problem
