Whether or not it's finished depends on where you're taking your trichome pictures at. If its the trichome on your sugar leaves, don't go by that. However, if indeed those are trichome pictures from your buds, then yes, you're in the harvest window. Some people like a more uplifting high and would start their harvest about now. Others prefer more of a "sedative" stoned high and those people would be likely to wait another week to 10 days.
If they were mine? I'd be cutting according to the breeder's recommendation, but that's just me. I've found through experience that since the harvest time is actually a 2-3 week window, it's better to wait than to rush into harvest.
