yep 100% hermie, thats defo a little ball, if its this early in flowering dont bother keeping it, it was probably hermie by genetics rather than enviromental factors.where did you get the seeds?
Ya...definitely a herm...you can cut off the pollen sacks and keep a close eye on the plant to make sure no other "footballs" appear....I personally kill any hermed out plants because another appendage could sprout ruining the whole grow...id make butter out of "it" quickly....good luck
