I would honestly wait as long as you can before you harvest. This is the worst time of the whole process cause you cant wait to chop her and give her a try and you have this battle going on in your head (at least I do) should I try some. You would be surprised how much more weight she is going to pack on in the last couple of weeks and those buds that are the size of your hand will shrink down to about a tenth of their size when you dry it. Just for fun last year I weighed one right when I cut it, it weighed 182 grams but two weeks later it was like ten grams. So long story sort wait as long as possible for full weight and full potency IMHO
