Gg4 wk8 how much time left

Well, it looks like it can go a few weeks. The bulkiness on it seems lacking too, and pistils are mostly fresh.

U might have light too close. White hairs look like new growth. Before u crop put her under 24hr dark that makes crystals an strength with aroma .. Keep checking the tri's look for a white milkie look

From my POV the tops are ready to go and the bottoms could go for another couple days to a week, but it also depends on how you want your trichomes.
