Looking at grow diaries of other purple rock berry, they show 70 to 75 days. Looks like she is finishing up.

Thanks for the feedback! Is it normal to see yellowing that quickly? This happened in the last 24 hrs.

24 hrs seems a bit fast, but I don't know about impossible. If I had to guess, you might have just missed the beginnings. Ripening can be somewhat strain dependent, some rock right on thru, others are a little slower. Have not run the strain, so no personal experience to offer.

Thanks again for the advice! Should I prune the yellow leafs or leave them alone?

You can do either. I usually try not to remove leaves late in flower, if for no other reason than it opens up the stem, is wet till it heals over... bad combination if nugs are dense or airflow is low.
If its wilting, I'll pull it, or shading another nug, but other than that, I enjoy the fall colors.

Yellowing is RARELY normal.. This plant is in a small pot and is under fed.. It is feeding off of the nutrients stored in the leaves because either there is no more food left in the medium or because the roots can't access it. "End of life" fade happens slowly, over weeks, as you stop feeding your plant. It's something we often see in organic/no till.. I have yet to see a plant that is being fed bottled nutrients up until harvest do a natural end of life fade.. End of life fade doest leave rust spots, and starts from the bottom and works it way up the plant.. A pot that small should be getting watered/fed daily.. That plant looks to have a few weeks left still

Thank you for the guidance! I’ll start feeding/watering daily and see if that helps.

Your plant is feeding off of those yellowing leaves. If you start pulling them off now, the problem will spread faster and the plant will have less leaves to feed on. Your plant needs as many of those leaves as possible to feed on make it to harvest. I would personally let them fall off on their own.
