Pruning during flower

just started flower period now should I cut off the young new growth that would normally turn into popcorn and leave the main stems to focus energy to them or just leave as is? if I should, what are some methods for focusing energy to the main stems

+rep if help

I trim off everything thats pretty much under the main canopy... especially in the areas that wont get much light... some ppl would say dont trim but imo i would def trim off those little popcorn buds to focus more of the plants energy in to the main colas
