They look very close. I'd say give them about 10 or 12 more days, though it is hard to tell without a close-up view of the buds. As for the yellowing leaves... Thats a good thing. Thats the leaves using up all the nitrogen. Once they run out of nitrogen the chlorophyll starts breaking down (chlorosis). This is good because chlorophyll makes the buds harsh and will make it take longer to cure and lose its grassy "green" taste. I would stop feeding it everything in a couple days and just give it plenty of water.

BTW.. they look good.. props.
