Thanks man, and yeah, if it's gotta be 400watts they're really bright compared to the same wattage HPS I think.

It's the White light that makes it seem so bright. Plus in most cases you don't need the bottom glass in the hood.

I don't know if I qualify here. I use 400w cmh but I have 2 bulbs in the hood. Here's the current, just one girl, kinda got skunked in the seed run 4 of 5 were boys. Maui Thunder day 31

4 more wks and she should be fattened up fine
 
I'm running the Philips retro 100's. The hood is made by Control Wizards it's 24x24 and is able to mount up to 3 bulbs.
I can only hope to have to add more support for the heads. Looks like you did some early toppin' & training to get all those colas.

Just got my 400W CMH installed in 2x3 room

This is right after first start up. Made a few flashes of bright purple and blue, It was pretty awesome to see

I guess I better get in here.. I installed my 400w CMH Bulb about 3 weeks ago, and the girls seem to be loving it.. I was able to remove the Cool tube and can keep the bulb 6" - 8" off the Canopy This pic was taken a couple of days ago and still in my first week of stretch. I figure another week of stretch should fill in the screen nicely.

I was curious about the height I could keep the light off the canopy, I have it air cooled (fan setting on low) I put my hand about 4" under the bulb and it was just fine. Right now I have it about a foot away, I guess I will be lowering it tonight.

Yea, I get it as close as I can without burning or overheating everyone. When I got the CMH Bulb, I put it in the CoolTube I had and you could almost lay the light on the plants and they would not burn, but I wanted to take the Glass out of the equation and make sure the girls were getting all of what the light can put out, so I got an Open Wing Reflector that spans the entire width of the room and am able to get that bulb pretty close.

The bulb kinda freaked me out a bit cause it does not seem as BRIGHT as the standard MH or HPS, but I think its cause we are seeing the full spectrum and not just a few of the colors.

Your set up is very similar to mine and I'm currently growing 4 plants in 3gal smart pots and it's a bit crowded. Next grow I think I'll use 3 5gal Smart pots.
 
start with CFL's to 250w HPS then switched to 400w HPS they are 54 days old... 2 x Auto Seed's HiJACK
lifetime: 70-80 days
2.3 GL pots
temp: around 26-28 C degree

almost all the leaves turned yellow, only the leaves around the buds are dark healthy green... Why it can be???Is it normal???

yea its normal. if you are following feeding right the drop in N plus the fact that its flowering is playing the part of the yellowing. dont worry
