Yes go with your reasoning and tie her down, you can get real aggressive too, dont be shy tie that bitch down to 45 degree angle, in a couple hour to a day her top will bend up towards the light but just however many inches lower that you tied her.
So, tie that bitch down branch by branch limb by limb.
This is my proffered growing method as it adds to yeild significantly.
Growing traditional trees is inferior, "LST" look it up, its a method of growing for maximum light spread and penetration and yeild, also can be "Scrogged" which is basically the same except using a screen for bud tops to poke through and be supported.
There is no other way to grow in my book, its superior, and more efficient, get in the habit of training them as soon as they are 2-3 nodes out of the dirt.
