your bud looks good but 6 weeks is too early, the reddish hairs will recede into the bud and it will pack on al ot more weight in the last 2 to 3 weeks also ur trichomes will start changing, the only way to see this is to get a jewelers lupe,strong magnifying glass or microscope( get a cheap 1 from e bay for less than $10 delivered). im at day 50 and i'm leaving it for 2 more weeks, then turn the light off for 2 or 3 days and chop and dry. i was gaunna chop this week but the difference in yeild and quality will be totally different i.e lots and lots more and it'll blow my fuckin head off. why go to all the hard work of growing just to screw it up at the end because of impatience? let it be buddy, you'll reap the benefits with some heavy duty weed.
