Indoor soil grow please help

I have spent my time researching books/internet over the last couple of years and I hope i have gained enough knowledge to produce a decent yeild (if im lucky to get females). I have one seedling @ 2 weeks strain unknown and 3 seeds (can be either og kush/some type of haze) that have popped and have been in soil for one week will post some pics soon...
I am using cfls just for seedlings.Need help on choosing to go 400 or 600w grow tent is 3x3 6ft tall. the local hydro store has a 400w with built in ballast in light fixture for $200 I think its a hydrofarm with no vents on fixture too cool it... is this a good buy or will i be fighting to keep temps down.
Venting??s what cfm would be needed to for inline fan to vent out the room?/and bring air inside of this size grow tent. also im trying to use 4in ducting but does not really matter.
As for nutes I will be using technaflora starter kit. I will start to gradually add nutes once seedling stage is over in a couple of weeks.
I have $400 to invest but in one month ill return to work so will have some extra cash to spend. Any tips/tricks/info thats provided is greatly appreciated... If anyones has any corrections that can help my set up let me kno positve and negative. Thanks Og...

pictures @ day fourteen

I see a nute burn on the tips that looks like it's a few days old, I see the whole plant yellowing which at this age is most likely a ph issue probably do to over-watering.

that all in one digital ballast is a great deal, but u have to buy an add on for around 40$ which is a fan that sits on top, then u vent through that. the 250 model non digital hps has an exhaust. I suggest going with a digital ballast/bulb/reflector. a yieldmaster reflector goes for about 110$ + a400 watt ballast+bulb will be under 400$ total. a 600 watt setup will cost you about 50$ more. you will need an inline duct fan+ speed control+ ducting, which can all be found at home depot. for a 600 watt you can get a 250 cfm inline duct fan for about 25$, then get 6 inch flexible ducting. buy like four 6 inch o-rings, and your setup is complete. from experience, i would go with the 600 watt, and if u can afford, go digital, cause u can interchange the bulbs, but the digilux bulbs are the best spectrum you can get. it will cost you a bit more at first but then you can continue to upgrade your system, versus by a whole new one. hope this information helped

IMO i would invest in some T5's florecents look at sunblaster then go to a pc repair shop and look for some pc Fans there simple to hook up i would use 2 of them for your exhaust remember to vent your exhaust high as heat rises and keep you air in low 4 " dryer hose is great with your 2 pc fans blowing out exhaust the air in will naturally fill in ur tent kinda like a vacumm cleaner effect as long as everything is sealed good your plants are far from ready for anything of 400 or 600 power

Thanks for the input when I transplanted it into that clay pot I used a very diluted mix of SugarDaddy and Root 66 thats what i was sure it was too nute burn because I keep the cfls 2-3 inch away from top so didnt think it was heat stress.... Ya I did add more water then I needed there is a little fan in there that is allways on and it dries the soil tops so me being dumb thought to water but I will take it easy on the watering.. thanks again

Thanks smokebros Im gonna look into going digital that def will save me money in the long run. DrFever I really dont want to use pc fans... Im looking at getting inline fans but untill I get the money pc fans will do I have one already, and I do understand they are not ready for that kind of power just trying to figure what route I will be going so I have everything ready

get the 600 w hps. buy a remote ballast and a good air coolable hood. something like this: http://www.htgsupply.com/Product-Digital-Greenhouse-600-watt-HPS-Grow-Light.asp i would go with a 6 inch fan something like this: http://www.htgsupply.com/Product-GrowBright-6in-Inline-Fan-&-Charcoal-Filter-Combo.asp. get these two things they are right around your 400$ budget and they will get the job done in that tent. ime if you grow in a tent an air cooled hood is vital if you wanna keep the temps down.

Todays pics any input on when i should transplant kind of wanted to let the other seedlings catch up first and what size container i was thinking like 5 gallon will that work or will I need something bigger for flowering??

Does this plant look retarded it seems to be growing weird on leaf isnt even serated another is growing under the biger leaf and on side of the plant seems to have better growth....
