Help with seeds

Im in my first grow and i only had one male and one female so i decided to seed it out. My question is when do i know that the seeds are done growing? Do they turn brown during flowering or do i wait until i have chopped here down and then they turn brown and finish. I searched all over this site and could not find anything so any help would be much appreciated.

You want to harvest the seeded female at around the same time you would normally harvest a unseeded female.

Just wait for the trics to turn 80% amber on the buds the seeds form inside of..
