Wait for it....Wait for it...CUT IT NOW! No just kidding. Give them another week. They will beef up even more and more hairs will be brown. But the best way is to look for cloudy tri combs. It IS your plant and if a brother needs a little bud than i say this is a good time to test yo shit!
ur plants look a bit 'cooked'. i dont know if its from too much heat? or lack of ventilation? or wrong fert at the wrong time? but the bud isnt as mature as the plant seems to be. certainly the bud leaf should not be brown and crunchy. sumthings up.
whatever you do man, just make sure you go and get like a gallon or 2 or just any kind of water....just try and get some thats somewhat purified and just cleen water. With that water, that is ALL your plants should get for the last 2 weeks of its life, in the last 4 days leave it with NO light, but still continue the water. then.....chop her . this makes it so the buds suck up allll the nutrients etc etc left in the leaves...thats why by the day you chop it practically all the leaves will be yellow. The last 4 day with no light thing tricks it into thinking its dying so it goes through that hole thing trying to make even BIGGER buds which ends up giving you alot more bud.......and such a damnnn smoothe/nice smoke. peace.
