No offence intended but, i consider this bad advice, why put all that effort in just to get less than satisfactory results. Your bud might or might not have some fattening to do yet. But it definitely has some terpenoid production to do, thats what will give your dope that real awesome smell and taste. Not even mentioning that the reason people on this site are never satisfied with other peoples crops is they always seem to get chopped early thanks to less than sage advice that is often doled out here.
I know it hurts now, but if you can just wait until those buds are "done" you will be so much happier in the end.
And as always, this is just my opinion, you should trust it just as much as you would anything you hear, take it with a grain of salt and make up your own mind. Just know that i tell you this from experience, if you wait a little longer you will end up with better bud in the end. (and possibly bigger) I'm not telling you this so that everyone can see what a smrt growing guy i am, but because i love marijuana and am saddened when i see people listening to advice that i believe will negatively impact their final product. IMHO you'll either wait it out now, and become a believer, OR you'll chop today, be fine with your bud, but always wonder if it could have been a little fatter, stinkier, tastier.... Okay im done, Just my 2 cents.
Whatever your choice may be, happy harvest and enjoy the friuts of your labours.
