Deficiency, light burn or neither?

So this problem has happened on a few of the outdoor plants the last few years. It's never been a huge problem before. On sublime og and Jedi I'll see a few leaves with this discoloration but this year the grape apes have been showing this more than I'm comfortable with so please help me out!

Looks like you got some nutes on them from watering, light burn on a mature plant like that is damn near impossible having them grown outside the whole time... Plus it will only typically effect the top growth
