Looks ready to me but ?

the canopy is done so you might as well be, because it won't be able to power much more growth. i see a lot of pictures showing sugar leaf trichomes -- don't use these trichomes to gauge when to harvest... only trichomes on the calyxes/bracts are what you want to scope and at multple locales throughout the plant... up top, middle, down below etc... and the average of what you see is what you want to go by.. it's more art than anything ele. 1 trichome coloration 2 pistil coloration 3 bud density.. use more than 1 metric to gauge when to harvest and you'l be more consistent about it. I've seen plants that will rot ont he branch before 10-25% turn amber... Some pistils turn faster than others... or maybe some foliar spray caused some coloration.. etc etc.. experiement on your own with early to late harvests... find what you like. I use this example: If familiar with nyquil... it knocks some ppl the fuck out, and others it makes them hyper. Chemicals we introduce to our body may have different impacts on your or me... in general later harvest will be more sleepy/couchlock, and early harvest will be greater % of THC vs whatever it degrades into. cba? also, "amber" is not peak THC.. it's far past "peak" at that point. Cloudy trichomes are first sign of degradation. plastic vs glass... when they look plastic they are usually good to go as another visual observation to use. have fun... can even try harvesting a couple colas early.. let the rest ripen and label it all as you go... then test them as isolated as you can.. like first smoke of the day vs after you've been smokign all day or smoked a bud from different harvest point just before etc etc... have a clean pallete to discern true differences better.
