Pruning 2nd week flower?? no space

My boy came over yesterday and after one look at the small space grow, he insisted that i prune off many of the big fan leaves and make room for new foliage and lower buds.. I was a lil hesitant to say the least but he went to school for horticulture and works in the feild.. he used to grow big plants outdoors.
So we did it, 11 plants at least 5 big leaves off every plant i mean big,,, the fan leaves were bigger than my hand. It did free up a lot of more room for the light to penitrate, Imade him keep his grubbl hands off of my fav. one so if anything i think we made room for the fav of the bunch.
Will this hurt the grow.??? =

and thanks for all the input everyone!!!

Probably won't hurt. Those leaves are needed of course but I think you can do without the lower ones...otherwise scrog wouldn't work...and if your friend has gone to school for this stuff he knows much more than I do...most likely.
Good Luck!
