Hi, i will start to inspect the trichs with my radio shack 60X, which buds or leaves should i use to check, top buds/leaves or bottom buds/leaves, or middle? 2) Can cloudy trichs change to amber in a day, or days? Thanks. 3) My Afghan,Bubba, and Master Kush, starting the 8 week, are mostly cloudy, are these 8-8.5 week strains???? Thanks.
