Trychome colour is the key, but from which part?

I have a few grows under my belt and can generally tell when a plant is ready, but it has always seemed to me that guides based on trich colour miss one crucial information, where to sample the trichomes.

My most mature plant is an indica dominant in it's 9'th week. Small leaves that stick out of the buds have milky to amber trichs and based on that alone, I'd cut her down now. On the lower side of those same leaves, trichs are 50% transparent 50% milky with no ambers. On the samle from the bud itself, trichs are mostly transparent with quite a few still headless.

Have you guys noticed such diffferences and what part of the plant do you take as telling (or do you take some kind of averake?

If you have several smaller branches that r not as mature as the rest u can always harvest top most mature buds an leave rest for wk! All the strains I grow I train or they auto there selfs to where it's all top colas. Much better this way because I like letting plants set in dark for few days, trimming the large leaves off then chop an hang upside down for 7-10. If u only have a few bugs that r little young I wouldn't wait on them if just chop. Now if half your harvest is immature then select harvest. IMHO thanks
