It's a crap shoot unless you can view those gland-heads, or have tons of experience, and even then sometimes.
If you're kinda new at growing, now's the time to take notes on everything . . . you just never know what may become relevant that never crossed your mind.
For example, my last grow 2 out of X cloned cured a golden brown, while X stayed green. The brown weed is perfect for me, the green, too strong. I have no clue what happened. As far as I know, I did the same thing I've always done, for 30 years. I have no harvest notes. Now I have to try and duplicate the gold w/o much data.
