No I realize the color of the trichs are what is important but before they get cloudy or amber they lift off the surface(golf ball on a tee ) of the leaf or bud what I was curious is how long into flowering are you when the trichomes first start to form and how long before harvest or when they start top turn amber.

taking off fan leaves just before harvest is appropriate to let the buds get the last bit of light I think about 10 days before harvest thats why I am asking trying to gage when to remove fan leaves by the trichomes stage of development? And wondering about how far into flowering they form and once they start how long approciamately till harvest ? The trichomes must have an average life span
??
thanks
