Thx sonar for helping him. +repLow Stress Training. It's bending th plant over and tying it down. It helps the plant to grow more horizontally rather than vertically and also opens the side and bottom of the plant up to more light. It's great!
Here's a great guide. The picture to me seems a little exaggerated, but you'll get the idea.

ive got 7 northern lights growing atm an that happened to mihne when the light was too far away, drop the light a bit and see if that helpsin the second week of growing some new northern lights and i feel that the hight is increasing too quickly compared to the developement off the leaves (not too bad). should i be concerned? solution?
I do this as well, awesome results so far.I use a combination of LST and topping.
