3 nodes hahah?

Yep, have seen it from time to time, one branch will start growing three nodes on an otherwise normal two node plant. Don't know why it happens or what for, just a freaky/funky plant thing going on, one of many oddities cannabis is capable of. It doesn't affect potency or growth, but is interesting none-the-less. If the entire plant is three noded (tetraploid), these usually turn out hermie or male in my experience.
