Don't sweat it. That's normal. It just means the pistol is past being receptive to pollen for reproduction. You probably have 2-4 wks to go, maybe a little more. What you will need to look at is the trichromes. They will go from clear to milky to amber. You don't want too much amber, at this point the THC starts to degrade. You're doing fine & you have a little while to go yet.~~~PEACE~~~
