I've done both cut down at peak potency and waited till the buds got more ripened and dence and I will never cut down early again. Yes the bud might be a little stronger at all cloudy but your loosing out on so much weight and slower burning better terp profile smoke. For a long long time I always obsessed over trichome color and cut when the trichs where all cloudy and 10% amber. You get a stronger head high but it dosent last as long and the bud burns very fast. Sometimes you get lucky and have peak density and cloudy trichs at the same time but more often than not they are cloudy way to soon for harvest.Now I don't even look at trichomes until I'm satisfied with my density first. Most growers cut autos down way way way to soon. Yes you might loss a tiny bit of potency but that's a small sacrifice to make for having 2 to 3 times the weight and density. Bottom line the longer the wait the more you get within reason.
