WTF!!?! Siamese Leaves? Flat Stem?

Let me know what you think. Ive never seen this before.

Nirvana Swiss Cheese on first week of flower. just showing signs a few days ago. This is only happening on one main branch, which also happens to be flat, something ive never seen as well. this branch is shooting out 3-4 leaves per node set!
Tell me what you think of the plant too! Grown under 150w HPS!

a mutation for sure, but what caused it? stress? part of the genetics? who knows! lol, thx for the interesting pics tho

its a genetic disorder check out the latest strain hunter video at green house seeds and there's a wild example of it. Only problem it cases is close to zero side branching from the flat stem. From the looks of it it doesn't really loose growth or anything but it does cause massive leaf formation at the crown.

woah! thats cool... its not a mutation, its just an old recessive pheno showing itself. i would keep it, it seems like theres more flowering nodes

wish it will go siamese trichs too , if yes i want a clone !
