It is still really hard to see the color of the trichomes. It's a lot better in this light though. As best as I can tell, they seem mostly clear and cloudy. I thought I might have spotted one or two ambers though, not sure. I'm going to believe you since you can get your eyeball right up close.

Usually there are more brown hairs at harvest time, but like I mentioned before that is not really a good way to tell. If indeed 5% of the trichomes are amber, then you could harvest now, or a few days ago, or in a week or two. And not all the parts of the plant have the same amount of amber, so you could harvest some that look more ready and leave the others until they are ready.

And yes, I don't think you would be a normal weed farmer if you didn't pinch some before the crop is completely ready. Won't hurt a thing. You could take a whole bunch off, like getting ready to reveg if you wanted to.
