jesus, shes really comin along nice, that pink colour is really showing alot, as for the trichomes its too hard to tell from the pic, the leaves coming out of your buds are called 'trim' leaves, and if they are curling upwards it could be that they need more light, or the temp. is too high, whatever it is, you shouldnt really worry, if you have been using nutes you should stop now, just give it clean water.
If i were you, i'd take a little bud, dry it and smoke it, if it gets u stoned for a long time, you might as well harvest, make sure its fully dried or it will not be psycho active, and now as your coming to the end of your grow put the lights on 14hrs night and 10hrs light, ive heard this helps to 'finish off' the buds, and they should get a little bit bigger, once they really slow down growing, and almost stop, i would say chop it, and if any buds start to swell enormously compared to the others, definately chop it, or your buds will turn into seeds, really the only certain way to tell is to use a shitty microscope, if you can get one.. hope you can sort something out, and make sure u post the harvest pics, one thing is for sure, its not long now... and when you do pull it, make sure you enjoy it, dont bother making hash from the trim leaves, just dry them and smoke them when you run out of bud thats what i did and it was worth it, as for the fan leaves, give them to your pets and they will love you for it.. X amount of respect rastaman m8, just wish i could come smoke a blunt or two with ya, till next time buddy...
