This is my first grow so please bear with me. I just found out that my plants should double during flowering (CRAP!). I didn't know this so I grew them nice and big before I switched to 12/12. I'm wanting to take several clones and thought that topping the plants might be wise as well. To top should I cut off every place where new growth is occurring or should I only do the center one? Also if I do this how long should I wait before I switch to flowering so that the plants are no longer stressed from the topping when I do so? Here are some pics. Thanks
