As mentioned in the earlier post I have been playing around with overdosing my plants as part of seeing just how far down the hobby rabbit-hole I want to go. What I see in your photos is the same as I have found on my plants.
The first photo below is one of yours from those you posted earlier today. It is a copy of the one you posted with the file number ending in 5703.
Circle #1 shows dead leaves and stems located close to the very bottom of the plant. Real good chance that even through those leaves are very brown they are not crispy and might feel soft and sometimes wet. The stems are dying or already dead but will not snap off. Any smaller buds inside this area have died. Once started this kind of damage can slowly work its way up into the newer or younger plant leaves and stems. I see what looks like the stems shrinking as the damage moves closer to the main stem. Same sorts of damage I have seen on my overdosed plants.
Circle #2 shows that the older and smaller fan leaves sticking out the bud have died back. Most of us accept some browning of the tips of the sugar leaves and most of the time we will be able to cut them off. Those brown sugar leaves might be brown all the way into the bud. Good chance that if you can follow the leaf Petiole (the stalk that joins a leaf to the stem) you might notice that where it meets the plant stem it is still thick and looks alive. But the closer the Petiole is to the brown leaf the skinnier it has become since it has shut down and is dying.
Circle #3 shows something that looks like a dead bud but I cant tell for sure. It could also be a bunch of dead leaves. If it is a bud that died I doubt that there are any tricomes left.
Then this photo below is one that was cropped out of your photo that ended in the file numbers 5610. Those little small white or gray dots on the sugar leaves do look like the typical damage done by Mites. I get the same sort of thing happening on sugar leaves. Thoughts are that this is caused by younger mites which are small and very hard to see which is why we do not notice them when we look at the tops and bottoms of the bud's sugar leaves.
Also the typical mite we experience on our plants, the 2-spotted mite, will survive down to freezing. I have read that most of them will tolerate below freezing if they are protected by going into the soil or under fallen leaves or into small spaces or cracks in the stems of a plant.
