At least another 2 weeks.
Pistils have not receded and the buds look small-ish.
If you want maximum production (and maximum harvest) then you did 'fug' up by quitting feeding.
Stopping feeding the plants in the most important stage of growth (late bloom) will lead to deficiency and reduce the production efficiency of the plant.
Plants don't store nutrients the way many people think they do, which is the main factor regarding the misunderstanding of the "pre-harvest flushing" myth.
It's up to you to do what you want, I'm just letting you know what is best for the plant.
Let the plants bloom until you see amber trichomes, then judge how the pistils are looking relative to the calyxes.
Or wait a few weeks and post some new pictures
