Setup fell, bent 70% of stems

Hokay, so, some fall out from my disaster. I have a pic here of an interesting predicament. The main stem split into 4 smaller stems, then back into one above the swollen part. I'm wondering if anyone has seen this before and whether or not the stem will continue to split or die off really. The stem is brown, most likely because thats where one of the lights rested. The brown part still feels moist to the touch.

Also, I'm curious what the swollen part of the stems where they were bent or close to where they were bent are, the swollen parts that is. Why its swollen, its function, etc.

Everything above the "split" (that's my name for it haha) is still living and getting fatter. So yeah, any ideas?:rastasmoke:

Second pic is just to give ya a look at the setup, I prop the small ones up, fyi.
