This is a good problem to have, each node will become a flower, resulting in more bud for you!
Now that it is quite advanced in flowering, it really is too late to be chopping off vast amounts of plant material, it could cause weird reactions, such as hermaphroditism or a delayed and drawn out flowering or even death, in the worst case scenario.
Any pruning needs to be carried out during vegetative growth, and at the latest, during the first 10-14 days of flowering.
Hope this helps, Organoman.
