Hey bud,
I would feed her twice more since I do not see any amber trichomes on the buds. The sugar leafs are no indicator for harvest, since the trichomes there can start turning amber weeks before they do on the buds.
After your next two feeds I suggest to water them casually with PH'd water for 1 1/2 - 2 more weeks before giving them a darkness-period of 36-48 hours max.
More than 48 hours can create a negative stress unless you run very stable photoperiod-genetics. 36-48 hours darkness is proven (some studies) to give the ladies a last boost of trichome- and terpene-development.
Furthermore, you want your ladies to have the last "thickening-phase" and yours definitely didn't have their phase yet.
Be patient, you won't regret it!
Cheers :-))
