OG Master Kush, first grow.

I posted this in Indoor Growing but then I realized it should be here instead. =)

This is my first grow. I’m growing O.G. Master Kush. Three of my girls got attacked by our lovely house cat, so they got a little catching up to do. I just put them underneath the 400W MH about 3 days ago and they are responding well. I have listed my specs and ideas below.
So, here are my specs:

5ftL x33inW x 6.2ftH
400W EIKO MH Bulb (for veg)
400W Sunleaves HPS Bulb (for flower)
Valueline 6" 435cfm exhaust fan
C.A.P. Reflector Hood with 2 6' flanges
Xtrasun 400w Ballast (conversion)
2 Isolating fans (they are not showing in the pics because I was cleaning them)
A/C unit in room
Mylar on inside walls
25" Exhaust ducting
Soil: Fox Farm Ocean Forest mixed with 25% Alaskan Humus.
Nutes: Forgot honestly, will post later.
Watering Cycle: once a day alternating nute days. I water them right when the lights go off and will also spray the fan leaves a bit.

My exhaust fan is connected straight to my hood on one side and the other side has the exhaust. Temps are anywhere from 78F to 82F depending on the weather. I’m planning on getting a humidifier, Carbon Filter and 4" intake fan to finish up my box. Any input is greatly appreciated.

More Pics October 6th.

Plants are starting to grow very fast now. One had spider mites and got a little stressed, but she will recover.

Been a while since I posted photos. They are a bit taller now but i'm not sure what is wrong, they are very stringy.
