First time grow! Juicy Fruit in Waterfarm Tent 600w!

Greetings, and thanks for reading my first grow journal. I am a medical card holder and have been saving up money for a while. I am a relatively new smoker and I have never grown a plant in my life. After seeing a lot of helpful grows here on rollitup, I decided this is the community I want to be apart of. I heard that once you go hydro, you never go back, so I am going to start off right! I am going to use Waterfarms!

The Setup:
DR120II Tent
600Watt MH and HPS bulb
Sun Systems Super Sun 2 Reflective Hood
600Watt Digital Galaxy MH/HPS ballast
Phresh 6" Carbonfilter
Vortex 6" fan with custom built noise reduction box (work in progress)
2' T5 HO Jump Start lighting fixture
2 Waterfarms with dual air pump and extra air stone in reservoir

The seeds:
2 Juicy Fruit Hydro Feminized

Work Done:
02-06-12: I wrapped the seeds in wet ro/di water paper towel and shut them in a CD case in a drawer for 2 days. Rinsed Hydroton 3 times and soaked them in ph5 solution.
02-08-12: I planted the seeds in 2" rockwool in tray with seedling heat mat.
02-10-12: Seedlings sprouted. I am watering them 3 times a day with ro/di spray bottle.
02-11-12: Added small fan on low.

I will be updating this as we go... but I would like some help from my fellow rollitup family.

Questions:
1. When should I switch to MH lights?
2. When should I start giving them nutrients?

Thanks in advanced for all your help guys/gals!

hey dude, You should switch to MH light Asap to let them veg as fast as they could with your best lights. You can give them Diluted nutes once the next set of leaves start to come out.

budsmokah-Thanks for the input on the lights. I just set them up.

***UPDATE***

02-14-12: Reduced ducting length 2.5 feet between filter and light hood. Reduced 1 foot from light hood to extractor. Setup MH lighting 3.5 feet above seedlings. I put my hand just above the plants tops and I don't feel any harmful heat. I have the lights on 20-4. Temp steady at 79F and Humidity at 29%.

Questions:
1. Is the Light the proper distance?
2. Do I need to increase the humidity?

***UPDATE***
02-19-12: I woke to one seedling drooping. Just the leaves were drooping like sad puppy ears. So, I decided it was time to setup the waterfarm! I could only setup one because they didn't send me two bags of the Hydroton. It is Sunday. I have to wait till tomorrow morning to get another bag. After 1 hour of putting her in the waterfarm with half strength nutes, she perked right up!

Readings:
EC: .4
Temp: 78.4F
Solution: 1/2 Tsp of Flora Micro, Gro, Bloom per 3gallons water.
PH: 5.9
Light: 38in. from top of plants.
