Hey guys just curious on topping and taking clones. I got this gorilla 5×5 with the one foot extension and the growers choice led 680 I have 6 Clone in the tent at the moment and was going to take a cut from each off the top and concentrate on the lower branches making them several big colas. However when talking to my guy at the local shop he said his commercial buddy has done side-by-side and has shown route die back due to topping plants please help as My girls are at the point to make the choice. Any info you guys have would be appreciated!!
