Very nice for cfl grow man. Beautiful buds. If you have a way to examine or look closely at the trichomes i'd go that route, I always take mine when they are 100% cloudy maybe a few clear here and there and a couple amber. I don't know why so many people like amber trichs on there bud, I have tried it many of times with numerous strains and mostly amber trichs mean the same couchlock high no matter the strain. Seems no matter what strain you have if you let them amber the high is all the same. If you want the true effect of the strain you are growing then I recommend milky trichs, unless however your needing the quality of what the amber has to give.
If you don't have a microscope IMO I would chop in about 3-5 days myself. Are the buds rock hard? and have the calyxes swollen up trying to submerge the hairs? Maybe cut the tops and let the bottom mature a bit more?
And a tip with the microwave. Put some bud in a paper towel and microwave for one minute. Take the paper towel out and you'll notice a wet spot were the bud was laying. Then put the bud on a dry piece of paper towel again, stick back in the microwave for about 30 seconds to a minute. And when you take it out let the bud sit for a minute or two and see if its dry enough to smoke. If not try another 30 seconds. And when you choose a small bud to do this break it in little chunks, helps alot, or at least thats what I do.
