OG Kush Fem, my first grow

They're looking nice. It'd hard to judge with photos. I would wait a bit longer until you see more ambers. Use a 40x jewelers loupe with led light works best. You can grab them off amazon cheap. Depending on the type of high you like 1/2 cloudy /milky with some clear will give you a head high. 1/2 cloudy mostly milky with a few amber to 5% amber will give you a combination of head and body high. Some wait until 15% + amber more of a body high. You can always harvest in stages by taking the main cola which typically ripens first then waiting 4-6 days to take the rest to see which stage you like better. Hope this helps you decide. Good luck
