Yellowing Drying Curling Leaves with Black Spots and Splotches in Late Flower

Hello. My plant is on Day 82 and prolly within 7 to 14 days of harvest, I think. As you can see in the pic, I gots yellow leaves with spots in late flower. Then they dry up and curl up. What does this mean? Is this normal? Is this a P deficiency? Do I need to increase nutes? Is she dying? Do I need to harvest her right now? This is my fifth grow, only. I've never seen this before.

I'm not flushing her. She's getting 1.3 EC right now. Heavy on the PK. (Liquid Koolbloom) She's in coco coir not soil. Haven't seen any pests of any kind. I've checked. No bud rot either.

What does this mean, in your opinion?

Thanks.

it looks like potassium lockout. Not toomuch of a worry seeing as you only have a short time until harvest

Phosphorus excess.
