Can you get ahold of a loupe or strong magnification of some kind?
Look at the trichomes on the Bud calyxes, not the leaves.
Clear- more heady or cerebral, short lived high.
Cloudy- considered by most as optimum
Amber- heavy body stone or couch lock effect
These are also strain dependant, which is why many find one or two strains they like, dial them in, and know exactly when to harvest for their requirements.
Hope this helps somewhat.
