no way. I'm no expert, but I'd say you have at LEAST a few more weeks. The for sure way to tell is to get a 30x microscope and check the trichomes. If they are all clear, they're not ready. If half or more are cloudy, it's time to harvest, or very close. When the trichomes start turning amber, it's definetely time to stop flowering! This is from what I've read, and not from my actual experience.
