They do not look to be in week 8 or 9, they look about half done in my opinion... They do not look very healthy either. Buds do not swell when they dry, the opposite actually. You will lose approximately 75% of your wet weight when drying.
Is that the nirvana white widow? I have a nirvana white widow starting 8th week on Monday and it looks comparable to yours. Maybe mine has slightly less red hairs. Could be that we both either have growing conditions that cause long flowering periods or we have bad genes (if yours are nirvana)
I thought mine would be ready at the 8 week mark but they are just now beginning to swell up so I won't be cutting until at least next week
