The only thing I personally would worry about at this stage is the browning of the bud leaves, and for a couple reasons:
1) This could indicate over-fert, and if you haven't flushed yet, you should do so immediately, as you intend to harvest this week.
2) When the browning of the sugar leaves progresses into the bud itself, it may be more difficult to manicure the buds to the desired neatness- if you want them to look good, you should really try to get any dead, browned, crispy stuff off the plant before drying the buds.

But that looks good. Nice work. I think the yellowing is at an appropriate level for this stage in flower. And the crystals are oh so sweet.
