Looks like your chopping very early my friend.
Another month or so and the flowers will more than double in weight, flavour and potency. Cannaboids and terps increase massively in the final few weeks.
As a rule of thumb I go for 95%+ brown pistils and swollen calyxs as my preferred chop. Sometimes 100% brown pistils and an extra week or two after that for max medicinal value and weight.
Enjoy your harvests my friend may your next ones be even better
