I vote for Potassium deficiency, with a Phosphorous deficiency creeping up a bit too.
The papery curled up almost burnt leaves look like she is short on potassium.
The splotching from the bottom up and the almost bluish tint to the leaves though they don’t look nitrogen heavy seems like a phosphorous deficiency that is progressing. The purple petioles couple be an indication of phosphorous deficiency as well.
