The Rez TWK does this same thing, out of 10 beans, 4 showed this trait.
It goes away after they get larger. It's a wax secretion not thc.
Rez's TWK is the first time I saw this, at first I thought it was fungus till I got the scope out. The one male I saved had this same thing happening when it was small like that, like I mentioned it went away after 30days.
