Pistils and bud ripeness, as midlifecrisis said, have little to do with each other. Heat can cause premature browning, while the trichomes are still clear. And at only 1/3 pistil brown-ness, under stress-free conditions, I'm usually looking at just starting the flush period, because I'm expecting another 1-2 weeks before harvest.

Here's the pic. bayimg - image: flushtimingquestion.jpg - free uncensored image hosting This is my third grow in hydro (DWC) and my last couple of grows were fairly harsh and chemical tasting. I want to flush for the right amount of time and am willing to sacrifice a little yield for optimum taste and smoothness. I've been using the Canna Aqua line. Rating: 5
