Are you sure that you are looking at the trichomes and not the pistils thats shooting out of your buds. The trichomes are pretty small and you need a magnifying glass to really get a good look at them.

If you look at this bud you will see the glassy trichomes in the back ground of the rusty color pistils. Hope this helps ya man. The trichomes are what you want to look at to gage when to harvest.

And very normal and will not fall off, you will be smoking them soon
