No it will be cool. Last grow I had a 2.5 oz cola on a Sugar Black Rose and the main stem on it snapped around 5weeks into flower. When it broke I quickly lined the stems back up so the plant's liquid can continue to flow and I put some package tape around it till it held it in place. It continued to grow with no issues. I think its a timing thing. If you get it back on before a air bubble can enter everything will continue.
