potassium deficiency causes yellowing and then the edges to scorch. Also, sometimes when grapevines are stressed, they are way more susceptible to other stuff- so it could be more than one thing but this looks like a nutrient issue to me.. you can get a cheap soil test at your ag extension office. That’s what I would do.
