I got Auto berry seeds germin.

How far away do I start a new 400 mh light from tops of these babies

A good distance for a 400W is about 20" away to start. If the seedlings are responding well you can move it a few inches closer at a time, and after they're growing fast, you can keep it about a foot away (as long as the temperature feels okay if you put your hand where your plants are).

I noticed they're a little droopy. Just curious, are you using anything to help control root rot, like Hydroguard? I saw the temperature is staying between 70-84°F, which is good :) Do you plan on separating the seedlings and giving them each their own bucket soon?
 
I was trying to go by distance chart I found on the site, I think my light was kicking Thier ass. I like the answer you just gave better. Being new to indoors I have no experience with these powerful lights.I did get hydroguard, I used it at 1/4 strength. I do plan to split them up. I just took a peek under the lid, bent stem plant has an inch of hanging out the net pot. Ph has hung around 6.0 -6.1

I just didn't understand that light should be the furthest away in the beginning, over time lower it closer to the baby plants. I may have missed that part some where. But being the professional noob, I dropped right down to around the sunlight equivalent. I used cfl to start my outdoor crops. Never a high intensity.
 
Thanks for answering! I'll check it out and just make sure to leave a little note about that. It makes sense you would want to put your seedling in sunlight! I should make it more clear :)
 
so it's been since sat and I think I got light situation fixed, checked on droopy leaves noticed rr plug looked dryish, the roots are starting right ato top of the plug.got squirt bottle with 6.0 h2o to fix that . noticed leaner had yellowing seed leaves and a root dropping from net pot. I was not sure when I had made res. water so I used so very little nutes. ph was good. I went ahead made a fresh resevior with 1/4 strength and hydroguard.
the light was too close. that's two rookie mistakes I made so far.

I wrote a little tutorial about common seedling problems here if you're interested :) If you do end up reading it (though it seems like you're already on top of it so I'm not sure if you need to), let me know if it is missing anything, or if I can add/change something to make it better!

I had the light at 50% and 13 ins, I turned it up to 75% and raised it 20 inches. I tried to give them a 4 hour dark period, but temperature dropped to 60f after 3 hrs so I turned light back on.

Hi Jibbler -;)

For heat keep the light on for 24/7 in veg they grow fast and the warmth helps them do it.

They look great ,PH at 6.00 . I wait until the root is in the water and the first food I siphon out 1 gallon of tub water and put 1 gallon of 1/4 strength nutes. and if everything looks good in a day or 2, change out the whole reservoir 5 gallons of 1/4 strength nutrients . It makes sure all is well for the baby.
Keep showing progress!

Agreed. Too much of a temp swing when she's so fragile is no good. Give it at least a couple weeks unless you get a heater in there or something. I think ideally, you don't want temps too much below 70 in veg.
 
I get to 62 at night but the water being in the high 70's keeps it okay till the big light comes on and warms everything again.
 
I looked in at the bubbles, seemed like like when I turned air pump down to 75%, there were more bubbles went across the surface. on full power seems bubbles just pop at surface in center of bucket.
which is better.
