Shoving some dowels or bamboo into your pots aren't going to hurt anything at this stage, your root mass will not be affected. It will be like you getting a small papercut on your finger, a little obnoxious but you won't die.
Your buds are so big they are not able to hold themselves up. Too late for a net but I used to tie yarn around the cola and just prop it up on anything sturdy above the grow. Support her she's a beauty!
