I am on week 8.5 of flower for a 7-8 week strain. At the very top of the colas about 30-50% of the trichomes are amber but I was told to check halfway down the cola which seems to haven't started changing at this point. I am not taking my readings from the sugar leaf tips showing through but from the parts that swell (seed pods if they had seeds). If I went by the sugar leaf tips showing through it would be time to harvest 30% amber) however I was told those change early. Most thrichomes are cloudy halfway down with maybe 1 amber in view under a 60x magnifier. It hasn't changed much in the past week. The strain in northern lights so it is a mostly Indica. Would you say I am ready to harvest? I was going to just flush one of my 6 plants and harvest tomorrow so I can take better readings. It is hard to get a reading when on the plant. My guess is I am ready but can wait for the different effect. When a seed bank says how long a strain is I figure that is the earliest for any real effect. I think waiting till 9 weeks for the other 5 plants would be a safe guess for the other 5 plants.
