Well I'm not of the expertise of others on this board, but I was always under the impression that those growths are just effects of growing a male plant, but I have no experience since I have never grown them. My guess is that its just the effect of growing the male plant which is giving an unusual effect since most males are killed once it can be differentiated. Then again, I don't know much about a more maturely grown male plant, nor what it would look like, so I don't want to be the one to make the call either. Maybe it was some crazy shemale mixup in some way? I'm interested in this too.
