I am 7 weeks into flowering on a rooftop grow of a couple of Texada Skunk plants and a few Texada Timewarp x Blueberry. I brought them in last night as it got into yjr high 30's and the next few days call for cold wet weather and possiblly snow. The pistils are turning red/brown but the trichs still look white. Should I chop? Pix are aabout a week old. Thanks
