They will grow up to the last 2 weeks of flowering. The last 10 day's is when they pack on most of their weight and the Trichomes get the largest.

The only time the pistils have an effect on the size of the flowers is when they are pollinated and then the flower produces seeds.
Zandor Reviewed by Zandor on . pestils at 5 weeks Okay, if someone were growing and the pestils were just starting to turn amber after the 5th week of flowering. Does this mean the buds are done growing? Or will they continue to increase in size? Can one expect that the plant is now turning to THC production? Or will it still build bud size? I know pestils are not the way to judge for harvest time, but they must mean something. This person is keeping their eye on the trichs, still all clear. Rating: 5
