First Grow Tent

Okay so my grow tent is relatively small 36x20x60 with 3 plants. I have an inline fan on the outside taking odor and all that other bad shit being sucked in through the carbon filter in the tent and expelling out of the tent. Temp is mostly 75-85 unless I turn it off for 4 hours for night time cycle and it gets 66f. I have an air purifier blowing on my girls for a light breeze and a cool mist humidifier inside the tent too. I do not have any air being blown in from the outside of the tent which I'm not sure effects anything. How does my setup sound? Seemed to burn my girls with notes but they are recovering. Really cluttered though...

oh oh and my light setup is 2 2ft 55w t5 5,500 lumen per tube and 5 spiral cfl 1450 per bulb all in 6000-6500k range

I'm guessing you must have passive intake (openings in the bottom of the tent). I would take the purifier and humidifier out and put them near the intake(s), and replace them with a small oscillating fan inside the tent. This should give your plants the space they need, and help lower the temperature (85 is pushing it).
