Well this one is a reveg jobby... I harvested the main plant back in April I think and left the bottom two unmature branches and just made sure I watered it when I watered the others. All I can think of is the parents of the Skunk somewhere in its linage had some purple traits that came out over the 9 months this plant has been growing. Because it didn't look anything like this before and I'll see if I can dig up some old pictures of it.
