I usually judge "doneness" with a few factors, although I don't usually subscribe to the Trichome clear/cloudy/amber school of thought. The buds look hefty and appear to be in the early stages of foxtailing. This is the most relevent signal that things are fully finished that I use. There are other methods, including the Trichome color change, but Sativa and Indica plants finish a lot different and the Trichomes alone don't always tell the full story. When buds start to get pointy and have a lot of single bladed leaves, it's usually time to start chopping. I prefer to let things finish fully, as I seem to get better flavor if I let them go until they have no more to give. The difference between the THC/CBD levels are very small between buds left on longer than recommended, which is one of the arguments that are used for using Trichome colors alone. Whatever works best for your particular style of growing is the best style to use... there is no right or wrong way other than over-mothering them.
and would probably be fine, but trichomes tell the true state of the plant.
