swelling of nodes?

k i have a beautiful nl/skunk thats my pride and joy in flower for 4 days now its feminized and im seeing growth at the nodes that confuses me. i deffinately kno what male and female sex looks like THIS IS NEITHER. right where they would show sex there is more of a half circle on each part of the node thats all swollen up an crazy. after doing research on this all i found is that it could possibly be the branches getting ready to fatten up nicely. like i said they look like a half circle at the nodes that looks like a blister you could almost pop. any help or insight is greatly appreciated. going to work soon so i hope to see the answer later tonight peace blaze a couple

ps i could take pics but its a camera phone and i dont want to disturb its light as the hps is to bright for the phone camera.

its cool had it happened in my last grow.i think its just to help the branches for the extra weight thats comming.

I'm in my first grow... 8 plants that have been vegging for almost three months... the healthiest looking plants of mine also have this. I wouldn't worry much.

phew cool ty. much relief this baby is my pride and joy little bush with mad bud sites everywhere! im happy now blaze a couple
