Why are my pistols turning red??

They have only been in flowering for a week and a half. But some of my pistols are already turning reddish/brown from the head down? Is this normal or are they trying to tell me something?

i was wondering the same thing, i have a plant that is doing the same thing, only a little farther along than yours. bump

Most times they turn red/brown from people brushing up against them.

If you are far long into flower with only a few weeks left, it is normal. However, you aren't.

Stop touching them!

depends on the strain.. i have plants that start turning as little as 3 weeks in.. others dont turn til 7 or 8 weeks in
