From what I have read and learned, you want to have your plant trained before flowering. Training during flowering may stress the pant and impact yields. I think you can do some slight adjusting as the plant continues to stretch, but the aggressive aspects should be done prior: example topping and fimming. I think with the scrogg you will train and bend for some time.
However, I am only on my second grow and would defer to some more experienced growers. 
I did manage to find a thread which gives a little info:

Here is another: I guess I have learned a few things! 
Continued success.
