The "fuzz" that appears on the leaves around the buds during the flowering stage is made up of trichomes which are little "factories" that produce the elements that make up much of the flavour, potency, and effects of cannabis. During the flowering process, the trichomes develop and start out clear, eventually turning milky white and then amber as the flowering process ends. A grower typically wants to wait roughly until the late milky white stage to the early amber stage to harvest (and the type of high one gets from the cannabis is sometimes considered to be associated with when the plant is harvested).
Getting clear photos of the trichomes with the digital microscope while they're still on the plant is a bit of a pain in the ass (hence the blurriness), but below are a couple more shots that came out okay. As you can see, we're still in the "clear" stage on this plant and this appears to be true of all the plants, though they'll each likely reach the important stages at their own pace.
You can clearly see the development of trichomes (appears as light "fuzz") on the leaves in these closeups of Colin Robinson's buds from yesterday:
And with that, here are the regular series of pics for today:
