In my opinion, no, your plant needs every healthy green leaf she has, to make the energy she needs to grow her biggest and best flowers.
Less leaves = less energy = less growth.
It is that simple and basic plant biology 101.
Defoliating during flowering is the absolute worst time to defoliate, but then again, I do not believe in defoliating ever, and especially not autos.
Hope this helps, Organoman.
