How long should I flower for?

I am just beginning week 6 of flowering and I'm not to sure what I need to look for to harvest. Just recently I have noticed my plants start to shrink it seems like. Does this mean that they are done and it is time to harvest? Any advice will be appreciated. Thanks!

you need pics.
but you should harvest when most of the hairs turn a golden brown
and when the trichomes caps turn to a milky or amber color.

6 weeks sounds too short id do some research on what i told you
and add some pics.

Look at one of the stickys. It should tell you. 6 weeks is way too early unless it's an autoflower or some ruderalis strain. Anywhere from 8-10 weeks til harvest for most strains. It all depends. The trichomes tell everything!

the tricombs just starting looking milky but the pistols are about 20% die back. I normally go about 80 % die back. This picture was taken a few days ago.

I would continue, be patient. Wait till at least 70% of the hairs are brown. That will be the easiest way to tell, with out making a mistake and sacrificing density. The last two weeks of flower are the most important, and when they put on a lot of mass.

any idea why it seemed to be blowing up in size and then stopped growing?? I agree week 6 seems too early. The plant is in a 8 in square pot and its around two and a half months old. does it need to be transplanted???

that looked like some banging ish what strain were you growing??
