yan402answered grow question 13d I wouldn’t pull the plug just yet. She’s still throwing pistils, so there’s some life left in her. Buds look behind, yeah, but I’ve had autos bulk up right at the end before. Yellow tips might be light nute burn or minor lockout, nothing I'd panic over unless the whole plant starts crashing.
You could do a light flush, reset the pH a bit, and just let her ride.
Worst case, you get a bit more.
Best case, she surprises you. I’d give it a couple more weeks before making a decision.
