After reading this:
"Calyx
swelling is a major indicator of peak maturity. The lowest, oldest calyxes swell first and the swelling works its way up to the highest, youngest flowers on each bud. At peak maturity about 90% of the calyxes will almost look seeded, they are so fat.
Three quarters to 90% of the pistils will have turned reddish brown as well. For a basic Indica this takes well into the seventh week of the flowering cycle.
By the end of the eighth week most of the calyxes will have swollen and a surge of trichome development has coated most of the buds. It is now that the development of a very discerning palate comes into play to determine the finest harvest time. Remember - patience is a virtue and often a discipline.
The ripening signs for most Sativas are highly similar, except extended over a longer period of time. Occasionally, some Sativas have windows of peak harvest that actually open and close. That is, for a week or so the plant may exhibit signs of peak ripeness.
However, a week later the plant may have a growth spurt, which lowers the trichome-to-fibre ratio and overall potency for a little while. Usually a fibrous growth spurt is accompanied by a corresponding trichome increase. Again, time and experience are the key elements in this regard."
I've decided to wait and let them open, cause they're definitely still opening. But the hermie is coming down tommorow, just cause I don't feel like picking ANY MORE NANNERS!!! haha, I see why people just chop em from the get go.
