Anyone have any opinions on this guys post? Here's the URL, but I'll paste in what he says:
Gland color will vary with ripeness of the individual THC glands, starting at clear, turning to milky, then turning to an amber color. There may be some exceptions, such as some of the Blue strains and Blackberry.These will have darker, sometimes purple gland heads. But by far and large, these three steps of ripeness will exist with the vast majority of strains on the market. The first stage, clear, will tend to make for a more cerebral, up high, withvery little body effect. Harvesting at this stage when little if any trichomes are milky yet, can be tricky. Harvesting too early can make for a beautiful marijuana plant that will not have much psychoactive capability! THC needs to "mature" to be able to pass its psychoactive capabilities down to the smoker. This is why I always recommend waiting until 50% of the trichomes hit the second stage: milky or creamy. At this point, you will definitely have a marijuana plant which has reached its genetic potential.
The milky trichomes have some "cerebral" qualities, as well as some of the more "physical" characteristics of the high. The last stage, amber, brings on a more sedative, physical stone. If this is what you're looking for, than I would recommend a sativa/indica cross, or an indica dominant marijuana plant.
Amber trichomes seem to ruin a sativa high if the marijuana plant goes too long. The above photo is a good example of a ripe marijuana plant: at least 50% of the gland heads have turned "milky," some heads are still clear, and a few are amber. This marijuana plant was harvested two days later.

I ask because I've got a lot of yellowing leaves and I tried out the magnifying glass today. I can see the trichomes but they still seem pretty clear to me. According to this guy I should at least wait until they start to cloud up/turn milky? And then I flush for a week? And also turn out the lights for the last two days?
