should we trim it up?

our plant is about 5 1/2 weeks old and there pretty vigorous branching so i was wondering if we should trim it up a little or just let it grow out

Let it grow unless you want to top it

You should really top it

I use a lot of bending techniques. Works out very well. Instead of one main cola you have a bunch of them. You should look into low stress training(LST).

I would suggest LST if you want alot of colas, very easy technique

Can someone send me a good link on Lst? tried searching but didn't get anything clear

A good trimming can work wonders along with a bit of LST.
