I've noticed that when you let a plant go for a while, the heads, as they mature, turn amber, and eventually dark brown if they go too long. If they go long enough, in my grows, I notice that the heads can shrink to a point where they're almost unnoticeable and it looks like just the stalk it there. IMO, it's time to harvest...
Are most of your trics cloudy or amber? I'm guessing yes... And always, if I'm having trouble seeing my tric heads properly, I change the lighting source I'm viewing them under. If' you are looking at your trics under HPS light, then you are probably missing alot, because the orange spectrum from the HPS offers no contrast to a amber tric head, so it looks like just another clear or cloudy tric, when in fact you have an amber tric. The whiter or bluer the light spectrum, the better it is for studying your trics. A bit of a blue light spectrum (like 6500k) contrasts well with amber or cloudy trics, really giving you an accurate showing of
