HELP! What causes this on the leaf? White and black spots.

[RSAgrower]

These two leaves are the first ones that I got hold of. It seems as if there is white spots with black dots inside. Someone please help! Thanks

Have you inspected the whole plant carefully to see if you find it anywhere else? I'm not really what it might be, but I suspect it's a pest...???

If you are using nutrients with water it may just be the leaf got splashed with the solution. it happens to all of us at some point...the leaves can't handle the solution concentration...only the roots can.

Howdy RSAgrower, If the leaf was from or near the top of the plant, I would suspect some minor light burn. What type of lighting are You using?

Hi guys, thanks for the replies.

The markings are scattered at few sites on the fan leaves. this is an outdoor grow so idk if it's a fungus maybe? I did do a foliate spray a couple days ago and it was in really hot weather.
