Should i cut off leaves ?

[big_a220]

Hi peaple i need a little help , My plants have run out of growing space , I just want to know if i could cut off leave's so my lower buds get some light ?
I'm growing blue cheese under x3 600watt hps room size 8'x7' and been in flower for 3 weeks

Thanks Guy's

i heard if you put a couple of low watt cfl's about 40 to 50 watts at the bottom of your grow space and aim them at the bottom of the plant that isnt gettin enough light that should work
