Plant about to die!!!!

yea... so.. transplant it if you want and make sure it gets some ventillation. i would keep the tent open or it will die. (also put the light further away while it recovers) if your planning on investing get yourself a 4" inline fan to pull old air out and passively bring in fresh cool air. it being trapped in the tent is the cause of your problem

^^^^
I would agree with that.
If you said the temp is hot, and you "left the tent unzipped a little bit"
... that wont be good enough.
Plants need fresh air, It looks like it is suffocating to me.
How is your ventilation system? Perhaps it is time to upgrade it.

im thinking of giving her bush doctor boomerang. any thoughts on that?

This is not a nutrient issue. Instead of giving her more nutes and compounding the problem, start with the good advice you're being given. Repot her into a soil mixture that has good drainage and make sure your tent temperature is about 75 degrees. Then leave her alone for a week -- the transplant will be a little traumatic and she'll need to recover. You'll know she's doing better when you see new growth taking off.
