yeah man, spray the seed case with water, wait a bit, then pull it off carefully, try to open the seed case up, it looks like its just hanging onto the end.
I have been known to fiddle with the babes at this age, with a pin to gently wipe that shell clear, but then again on a few occasions I wish I hadn't ...your choice ..lol
I had this happen with a few of mine. When it was good and ready to come off I helped it off. The plants then surged in green growth. Me I would wait a little and then probably just pull it off when it nice and wet.
