Nahh man, try and take clones from some secondary/ tertiary colas, give them a nice long stem, cut near a node (easier to root from there). Find one with some small healthy leaves on there. Put the clones back to an 18/6 or similar light cycle. Keep the plants warm, but not hot while cloning. And if you manage to root them, they will likely sprout multiple tops. The first leaves will be oval shaped, no serrations. Then they will turn normal, 5-fingered. Then you can put it back to 12/12. Some people have said it increases yield 30%, I have only done it once, and I didn't really have much to compare it to, so I don't know how exact that number may be. People call it monster cropping I think if you want to look up the thread. And it is normally done around 21 days, so be extra cautious and quick with the clones, because flowering plants aren't really supposed to root, haha
