I'm with hotrod if you want to clone her this are perfect to root out. If you don't want the clones I'd still trim them out. Those would just be larf/ sucker branches. They won't add much to the yield, in fact I'd say they take away from it.
As far as when? Do it now, do it later, your choice. I would advise sooner rather than later so she has time to recover before flipping her. I'd say by the 15th if you're trying to follow a schedule
