Personally, listening to the trich development and looking at the plant it is too early to chop. Understand what Althor is saying but believe this is generally an exception to the rule. This plant although looking very beautiful does not yet look ripe. I think the leaf colour is not due to the plant becoming ready but other factors. I would wait, the hairs need to recede more into the buds and turn reddish/brown more. If you do wait just ensure you have good airflow to the bud sites, and chop after a min 12 hour period of darkness. Your call.
