The bud in this picture is well and truly ripe and ready for harvest.
10-15% amber is my personal preference, but some genetics will be 70-80% amber from about the 4th week of flowering and have honey coloured buds at maturity......it's all about the genetics of each individual plant.
I have played around with partial harvests over the last 40 years and do not ever do it any more.
After chopping the most ripe buds off and leaving the bottom bits to "after ripen" does not work in my experience.
Chopping large parts of the plant off causes a huge metabolic shock..........the plant then goes into some sort of coma and the left over buds never get the quality of the first picked buds, no matter how long you wait for them to "after ripen".
It seems once you chop large pieces off, the plant is unable to function properly (makes sense to me) and the left over buds just sort of stew rather than achieve greatness.
Even when left to "after ripen" the buds from the second pick never seems as good as those slightly under done buds from the first harvest.
These days I always harvest the entire plant in one operation and accept it for what it is rather than hoping for a maybe/could be.
