could i harvest this plant early ??

loads of white hairs is a very good sign, it means the plants growing bud quick, but needs a few weeks to fill out
know how you feel, my plants are 7 weeks in flower with lots of large buds, some over 2" thick and 6" long, most had brown hairs on so I planed to harvest Friday
went in there an hour ago and there covered in white hairs again and as its the last harvest before Christmas, I will just have to wait it out, could take 3 weeks more, not happy as I have just run out
but this will increase my yield loads, so it worth the wait
