Afghan Kush Ryder - hairs browning.

Hi all,
Below are pictures of the Afghan Kush Ryder, The hairs have started turning (25-40% now) but the buds still seem pretty small, I am sure they will swell up at one point, can anyone give me some advice on when this will happen?
according to the seed bank the Afghan Kush flowers for 55 days till harvest but mine has been flowering for much longer.
I have just run out of nutes so will begin flushing today if it wont hurt the plants otherwise will have to have a walk to the next town next week.

do you know how many days you have been flowering?

61 days to date they have been flowering.
there are tons of bud sites and buds but they are rather small, just wondering when they tend to swell and if they look near that time? cant wait for the buds to get bigger and closer to harvest. From what i have seen the trichis are mostly clear with a few turning clear.

cheers
