Yes those are the top two colas, we kept it small due to limited space. Through veg we honestly didn't have enough light on them but the buds look like they're doing nice. We have about 350 watts on the two plants now. But no we don't have a microscope I figured I could look at the buds and tell when they were done. We're about 6 1/2 weeks into flower.
Id say your about 2 weeks away. For almost any strain I would wait at least 60-65 days. I've been taking advice from a seasoned grower and he said anytime he cut before 60 days it affected potency and his overall yield
