Too crowded?

Hey guys,
I have one of those good problems to have.

i have 3 plants lst'ed in a 4x4 tent. They have filled out nicely (currently day 17 of 12/12)
I am a little concerned about them being too crowded.

im not a proponent of defoliation, but I'm considering taking some leaves off, just to get better circulation. Or should I leave them be?

what do you all think I should do?

Do u have any fans oscillating to promote air movement? I'm not a fan of defoliation either. IMO That's like going to the doctor n them saying well u have a fever so were gonna have to amputate ur fingers! Lol.

Thanks for replying

i do have two small fans in my tent, one clip-on type going over the canopy and a pc fan down low, blowing up into the plants.

and recently I have been leaving my tent open during lights on, with an osculating fan directed onto them.
