Well the best guess is they are slow developing females. They seem to form the same colas of buds and have no sacks they just look really green. It's really odd. And those plants had been given plenty of nutrients. They just stayed that way. He said the seeds may have been from a female plant that was polinated by a hermaphrodite so I'm guessing it might be something weird with the genetics, but he had no male plants and no confirmed hermaphrodites from the seeds. Pretty good odds.
