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.

Hi, when 1/3 of the pistels have changed coulor = More of high.
when 3/4 of the pistels have changed coulor = Heavier smoke.
Hope this helps you.:thumbsup:
