Nute burn maybe?

[Jordann]

I have one plant showing these symptoms whatever it may be, shows up more under the light but these are the best pics I could get, proper feed, ph, calmag all that and not burnt tips and completely happy plants aside from this girl, showing on the biggest of leaves, new growth unaffected. Maybe the leaves are just tired, like me. Any and all input is appreciated as always.

Well! It’s not nute burn in my book.
If I had a plant showing this, nute burn wasn’t on the list.

you mean all the red dots on the leaf right ?
