yea id say at about 5-6 weeks since in a few hours its April.
Most the pistols have changed color and the calyxes are beefing up so i may in the 3-4 week stretch.

your ladies look really good by the way.

thanks

ok just started seeing some amber and i was told once not sure if is correct that there is a 5-7 wndow where the thc degrades,,so would that mean the trics would be now turning amber at a fast rate in a week or so.??
