Only one side of plant growing

Has anyone seen this before? I've tried search and Google and couldn't find anything. It's growing good as are the 3 other plants but this one literally only has half a side. Its a freebie from Nirvana which all my other freebies have been great. I have a feeling I'm going to have to support this one as it gets bigger so it doesn't lean to far over from weight and break.

Did you damage the top at all any time during it's veg period so far? It looks almost like a topping with the other side missing.

Nope it grew from seed like that. When it first popped I was like man that's weird looking and from there only one side grew. None of it died off or anything just never grew

My first thoughts

Weird. Take a good picture of where the first node starts.

Here are a few more photos up close

Must be mutation, very interesting
