Fim'ing is easy... when you look down at the top of your plant you will see a grow shoot and two little branch buds next to it, sometimes you need to sperate the already grown leaves. Instead of cutting off the newest grow shoot completely, you want to cut off 50-75% of it... when it recovers you should have the two branch buds come up strong along with the recovered grow shoot.
Does that make any sense? I know, pictures would help, sorry.
