First of all, how long have the plant(s) been flowering for?
Even a guess will help more than nothing, your plants look like they are in a bit of a nutrient deficiency.
However that is quite normal for late blooming.

You need to check the trichomes if you want to be sure about when to harvest, otherwise it's a judgement call based on bud density and look.

i dont even know what week im in i lost the paper i wrote it on lol but yea i just wanted a guesstamite thats all

it looks like you've got at least 3 more weeks

thank u marcu

you still have a lot of pistil still sticking up and they haven't even started to change color or receded back in the bud I know trich are the best way to tell but the pistils are another and looks like another 3 weeks left IMHO

thanx smoke +rep 4 u

The only real way is the watch the receding of the hairs, density formation and general colour of the buds and trich colour changes.
I have seen buds with white pistils and amber trichs.

If you want a guess, 2 weeks.
