They look perfect :)

I assume its 4 weeks from germination?

And do not move the hps closer :S - At this stage they are very fragile and excessive evaporation will surely kill them. - Using hps from start will generally make the plants stretch a bit but i view it as a plus when the plants moves onto the next stage :)

Oh, they may do some stretching if your vegging with just a hps lamp.

Get a daylight 42/45 Watt CFL to add some blue to your spectrum. Get two if you can. A MH would be ideal.

It will work with what you're doing, but in all likelihood you will get some stretching.

They also may mature quicker with all the red they're getting.

You may also get pre-flowers even before you get to 12-12.
