It looks like you are well on your way. Great looking grow my friend. Possibly 2 weeks longer for sure to get some more bulk.
It also depends on how developed your Trichomes are. I use a small handheld microscope to check my Trichomes and harvest when about 70-80% have turned amber in color. That percentage can be based on your liking and is just a general rule of thumb.
I suggest getting a closeup look of your bud to see how cloudy and amber the Trichomes are and make your choice based on that. Be mindful that some genetics and amber up in the matter of a few days so just keep a diligent eye on it.
Hope this helps.
