Thanks for posting that link. The section on trichrome color was good reading. It talked a little about how the various strains show color differently and there isn't a hard and fast rule regarding the progression of trich color. You gotta get to know your strain...
I like to cut the entire plant and hang upside down in a dark room for 2 or 3 days. Then, remove the large fans, cut down to individual colas and hang those in a dark room for a few more days. Then, de-nug (is that a word?) the colas and alternate between jars and brown bags until it's dry enough for jars only.
