you can trim off the newer undeveloped pistils if you want. you could wait for them to ripen.
i'm not a fan of 2 drastically different timelines for ripening. but, you may feel differently on that. The main concern i see here, if you go longer, is that the canopy is decimated. Not much photosynthesis is taking place compared to before. So any development would be slower, too.
fan leaves dying could be senescence at this stage and not a concern, though not good for pushing on longer, obviously. However, just to be safe, look under the buds in an area where fan leaves have turned brown and crispy. Ensure there is no white or grey fuzz along stem underneath the buds. Find a spot you can gently pry it open slightly to see.. you don't have to damage anythign to do it, if you do, just pull off that chunk and let it dry somewhere and you can smoke it in a few days, lol. it won't be lost and won't cause any problem with plant, just not optimal, so try to avoid it.
1 spot check is fine.. if not infected the other areas died by natural means too. you don't have eto tear up your plant to check this.
