Don't let the plants fool you. Always look at the tops of the plants to know when they're done. That's the last to develop and ripen. The white hairs that turn orange, red or brown are called pistils and are the receptors that catch male pollen, creating seeds. You want 80-90% of these to have shrivelled and turned red or broiwn, particularly at the tip of the top colas. The trichomes are the suggary crytal resin glands over the surface of the buds and small leaves. These will swell to look like tiny crystal mushroom heads (have to usae a magnifier to see this) that will turn from clear to milky, then amber as others have mentioned. Ideally you want to catch them right as they begin to turn amber, just barely crossing the point of peak potency. This happens over the course of just a day or two, so watch them very closely. Odor will seem to nearly double with pungent and noticably, "ripe" smelling reek factor. I agree they look like they have about another 2 weeks to go in the pictures. WW is not a particularly fast strain. Wait till they're done if at all possible. You will be disappointed with both yiueld and potency otherwise. Even slightly imature buds will lose much of their odor and shrink far more than you'd expect. Just remember that they'll look done at first when in fact they're not.
