today is monday as I write this. If you wait another 6-7 days to bud, just be prepared for the size it will become as they continue growing in flower. It's not real big now, but after 7 days in good hydro it should be twice the size it is now. If you wait to flower, you might end up sorry you did. You can try it and see what happens and always make some cuts if you need to. It's looking real good so far. You could try cloning if you want while it's still in veg. It's going to get real stinky, so be prepared for that. I hope you don't have curious neighbors. I grew a sunflower once in DWC to six feet in just few weeks. Pretty cool.
