Topping my plant...

This is my first grow so any advise would be appreciated...

I topped it at about a month old or so, It's doing well, but should I top it again?
It has 4 top looking branches... about 12" above the origonal place where I topped it.
If I should top again... do I do ALL 4 of them? or what...?

Oh, its about a 6 weeks now...

check this thread out. should help.

well honestly I'm not shooting for super massive yeild, I mean, yea, the more the merrier but, this is more of a learning venture...
Like... how bad would it hurt to take like... 1?
Just thinking to see what happens...

Is it generally standard and proven that topping once = 4 colas = best?
or what...?

You can top it as many times you want and will prolly get the same yield maybe a lil different but usually once or twice is the best option
