It looks like they need a few more weeks still to ripen if that helps at all. What medium and nutes are you using?
They look great. I've been using the same FFOF for 10 months now, but I only use organic nutes to keep my microbes happy. But ya, I almost made the mistake of harvesting too early last time. Really easy to do. I learned to only use the breeders flowering time as an estimate. After last time with help from everyone here, I know a little more now of what to look for. I watch for pistils receding and calyxes swelling now before I check trichomes. Looks like your gonna have a nice harvest. Congrats.
