Only one thing to do at this point. Eat it!. I love eating the tops of the young plants when I'm doing early trains. Sometimes give me an idea of what the plant is going to be like. Mostly tastes like a spicy cucumber.
You don't have much time to lose. You need to IMMEDIATELY find a quiet place to sit down, RELAX, and smoke a bowl. Everything is gonna be ok.....ok....
You can give it time to recover if you want or just flip to flower, both options should be fine.
I am more prone to giving it an extra week to recover.
