As some of these older pilstils wither the other pistils begin a visable transformation in color from white to orange, red or brown.
1. less than 5% of the pistils are withering
2. approximately 90% of the pistils have reached maturity
3. less than 5% of the pistils appear to be in the early stages of growth
The 90% group is the one that you should gauge your harvest with.
Brown hairs can also be a sign of pollination. I don't give any nutes the last week or two of flowering. If you're not sure, take a sample!
