Heres the pictures guy’s. Need you again on these BD Autos. Outdoor. Yellow leaves. White spots, nkt fungus or mold , it wont wipe off i guess light burn?Was 100 degress every day with ghetto fan. Now have upgraded airfl0w with clip on and 3 fans . Stays 85°
If you don’t spray them with anything then I would be willing to bet you’ve got bugs.
You may need to get a scope and look on the back side of the leaves for small bugs. Too small for the eye to see. 
Looks to me like you may have spider mites.
Zoomed in on pic #3 and can see the webbing on the leaf fringe.
Capt jacks dead bug will take care of them and you can spray it up till just before harvest.
I’d suggest a bud wash at harvest too.
Good luck. 
I sprayed them with mighty mint peppermint spray a while back and saturated them now. Ive used a kelp and superthrive foiler spray for possible zinc mag defic. Idk.
@Oldguy not my grow but curious if you can ss and circle the area you are talking about? I don’t have spider mites myself but I love learning and would like to see what you see! I also can’t see it myself as I’m noob 
Looks like spider mite problems, I had this last week also. But wasn’t on this level and was only a few leaves. Get a magnifier or a loupe and check the leaves and the underside of the leaves for eggs
Check the leaf fringes and you’ll see the webbing with a couple on it.
The tiny darker spots are their
