Using the grow, micro, velokelp and magnifical. I started the seeds in rockwool cubes and moved them to the buckets when the roots started coming out the bottom of the cubes. The system takes 20 mins to fill and drain completely.
I could turn half the lights off as the LEC 630 has two 315s in it and you can turn them on and off individually.

You need to treat rockwool like dirt a bit as in you dont want the base of your plant being wet all of the time so make sure the bottom of the rockwool is just touching the top of your water line. Stretch or not.
I like what you did in your room, I know what your room layout is dictates what you can do but I recommend that you move it to the middle of the room to get away from the wall. The light spread of your lights you get alot of cross over which is good but if the lights were turned end to end {you have them side by side} you would still have coverage on the end and a wider light spread from side to side of the room to accommodate the plants better when they get bigger if they were in the middle of the room to get away from the wall.
I used to have a room like yours all packed in there like that. So I am going to suggest to eliminate the middle row in the layout you have now or the layout I suggested as they are going to get too crowded when they get bigger. Been there done that situation. It gets unmanageable. Four plants per light. I cut my room back to two lights and eight plants yield wasn't effected that much Every now and again when a plant getting the good side of the light starts to out grow the other side you can spin the pot in the green container to try to get a balanced growing plant if that makes sense.
Why are a few of the pots on pads is there a dip in the floor or did you want to lower the water line in those pots? Just curious. I assume that since you have nonvented hoods and run c02 you have a sealed room which means you are running a/c which means your not exchanging any air but I still dont think little seedlings need 8oo ppms of c02 I dont think you need any c02 right now just a fan blowing around and it should be ok. To save on cost. They are not going to use all that c02. I also think if you can shut off one side of your light to save on cost, their little seedlings, then do that and lower the light down a bit. Then one week run one side and the next week run the other side to get equal wear and tear on each bulb in the hood.
I also have a chiller, I dont have a/c, I dont keep my rez in my grow room although I do have my control bucket in the room like you do. I did wrap my rez with an insulation blanket you use for water heaters, It keeps my rez water cooler longer and doesnt make my chiller run as much, this was a considerable improvement since I dont run a/c in my grow area. again to save on cost.
I think that you are trying to push them too fast you need to slow down and let them get bigger till you push them.
