Looks like nut burn to me? Maybe even a lil light burn

The taco of the leaves tells me heat and or light to much of

These autos can't take the light I had the same issue man it's definitely lights but u look like u came in a lil hot on nutrients also

What is your light intensity at and how high over the plant is the light?

What nutrients are you feeding and at what dose?
While it does look like light/heat stress, leaves at the bottom of the plant are also showing symptoms so I think there's more going on then the light.

Some toxicity and deficiencies can make a plant more prone to light and heat stress but need to know what you're feeding and how much.

Can you take pictures of some of the leaves close up so we can see the symptoms better, take some of the severe leaves and some of the lower leaves that are not as bad.
