You can tie down your tops to allow light to get into the inside of your plant, but to really get your lower branches to grow like tops you need to take off the very top nub. You usually start this with a very young start, but on the top shoot spread the leaves gently,
to where you will find the very small top of the plant, (timing is important too) it will be a very small nub that eventually grows out to be a top. You want to pop it off, it should easily fall off. (I use a tooth pick)
When you remove that top, it triggers auxins in the rest of the plant to have the side shoots grow, and they will become super tops.
When you do this when the plant is a few inches tall, before it stretches or starts growing side branches. you will get 2 nice uniformed branches, then you do it to those two, and you will get 4 nice uniformed branches...so on and so on.
As she grows out tie down the branches, soon as they grow you will get a branch start in middle of your tied down branches.
You pop the top off it, and it will produce 2 branches...ect..ect..
Now if you have done this correctly and she has grown normally with out a lot of twisting on pruning she should be uniformed and have a spread of identical branches through out.
this girl was only partially topped, I did do the side topping and so on, but on later girls I did, just haven't any pics of em
