For lots of different reasons, a lot of plants will not progress in their trichome stages in a linear fashion. Overall health of the plant, genetics, environmental specs, etc. all influence the finish.
The plant looks ready to me but pics are no substitute for seeing in person.
Rarely do growers let their plants grow too long, but I’ve let plants go several weeks beyond my usual standard, in hopes of more amber trichs. The amber trichs never came and there was a noticeable loss of terps.
Id chop and be happy for a nice looking run.
