My lady is tied down.

Noob here. This is my second post.
This girl was started from seed. I got some Aurora Project seed from 303 seeds. I started with 8 plants.
Seven turned out to be males!!! So.... that leaves me with this one solo female.
I topped her once early in veg. She's been flowering like 3 weeks now. (Luckily, I got the males away before she pollenated - I hope!)
Any how, she was 51 inches tall and I decided to do some LST yesterday beacause some of the lower cola sites seemed like they could use more light. Plus, I want to maximize whatever yeild I can get because I only have this one girl now. Im hoping that the branches will fill in and become heavy as shit. The plant is extremely healthy and growing like gangbusters! I've put up before and after pics.
Thoughts?
Did I do bad waiting so late into flower to tie her down?
Do you think the LST will help?

Absolutely it will help, good job brother!

Thanks Direwolf71! I figure with probably about 8 weeks of flowering left to go, I should be alright.
Hopefully, I'll be looking for ways to prop up the branches soon!
Here's a close up of one of the buds from this morning.

Damn...7/8 males. That's rough. Good luck with your lonely lady.
