1 never dim your ballast.......the ballast might dim but the bulbs are not designed too they are ment for a set watt to pass tho them to work correctly ( ie the right color waves and power) running a bulb on a lower watt does damage to the bulb shorting the over all usable life .....if u up grade look for Select a Watt those do 1000 600 watt bulbs great
2 your carbon fiilter move it so it is in the center of the tent right above the hood ......u want the suction to be at the hottest part of the room to get the most effect
3 have u run the fan on full power with all doors closed and only the vents open(does it concave in if the pass vents only )

make a powered intake for your tent .....using the booster fan will keep a negitive pressure in the tent but not so great it concaves the tent in
4 what the other person said about a fan .......they are talking about in the tent to blow over the tops of the plants to remove the IR heat build up on the leaves .......simple trick get a paint can with 3/4 to full for the weight take a peice of pine fur strip (98 cents for 8 feet home depot) cut it to about 4 or 5 feet......then set it next to the can and duct tape it around to the can 20 times or so ....u made a stand a 6 inch clip on fan can hook to and use it in your tent with it taken up little footprint
5 i am guessing u are on MH bulbs ......these bulbs make less IR heat then HPS .......so test your HPS in there before u get to deep and run into oh shit problems scrambling for fixes
6 and relax this is ment to be fun u will not need to buy weed again ......as for what happends do not worry the crops keep getting better as your skills get better
