It`s just a random mutation.I`ve had more than I can mention over the years.Although,one mutation turned out to be quite a keeper.It may or may not be worth growing out.I generally rip em out instead of wasting time and space on something that likely won`t do well.
The pics are so out of focus,that I can`t make anything out.I don`t think its botrytis as that would show as large gray/white patches.The plant looks stressed at any rate.Not sure why it is displaying flowers at such a small size,unless you started it flowering.
I would have to think that there would be a difference in forcing flowering,and ripening fruit in a food crop,as opposed to growing mj.We have the abilty to force flowering in mj by manipulating the light cycle in a controlled environment.Ethylene gas may be useful to force ripening in a fruit...
