If you have a microscope of some kind or a magnifying glass check the trichs to harvest a bud with desirable high. The more opaque to amber trichs the more couchlock, the more clear trichs the more head high. The trichs will be mostly amber in the end of the harvesting window. Can not tell you for sure from the pictures if its ready to chop down as each plant differs, when I harvest my indicas they have almost each of their hairs reddish, but still I double check with a scope.
Tasty looking buds btw!
