Could it be as simple as nute burn or am I missing something?

I would agree; short on Potassium. Good luck.

I had similar leaf issues and never really nailed it down but suspected K deficiency too. I was using canna coco A & B at a low strength, about 5ml/gal.

I don't know where you are in flower, but if you feel you're short on Potassium, find a source of Potassium and add some to your mix...but don't over do it. If you only have a few weeks left in your grow, I don't think I'd do much except take notes and apply what you learned to your next grow. Good luck.
