Putting them in darkness for 48 hours will just stress your plant and is totally un-natural, with dubious principles and is an urban myth when it comes to being of any real benefit to quality or being of any benefit of any sort.
I would not want to harvest a stressed plant.
After looking at your diary, I would say another 5-10 days, taking into account what gmslave said, which I agree with what he wrote, soon for a THC head high or later for a CBD body stone.
Hope this helps,........
