Peebz Looking great ole buddy, nice job.
Don't go by what the Seedbanks say, go by when all the pistils have turned brown-red, and have receded back into the buds.
Some pistils don't always turn redbrown, but most of them do.
Also go by the trichs on the calyxes, not the sugar leaves, the sugar leaves always show amber a couple of weeks before the calyxes do.
Your plants are very frosty, nice brother, keep up the excellent job .
You are doing great, your buds will only get fatter, by waiting, and in 3-4 more weeks, you will have some excellent smoking ,powerful buds to be proud of, that you can enjoy, with your Wife, and friends, that you trust.
Have a great day Peebz,
HappyGrowing
