Thank you for all the help everyone. This site is very informative.

My next question is how to top? My last harvest, a friend of mine topped them and they were short and bushy. I'm 10 days into flowering and this harvest is as tall as the last one when finished! Is it too late to top them now?

Also, when my friend topped them, he said there's a way to cut the branches where 2 will come out from each cut? I'm kinda retarted when it comes to this so detailed explanations would help. Thanks again everyone!
