Also man, whenever you transplant, just bury all the plants up to about 1.5-2 inches below the bottom leaves. All that stem that is put underground will convert to roots. Just be careful in the meantime (maybe use some more stakes to hold them up) and if you get an oscilating fan that blows on the plants like in my pic it will help fatten the stems up a lot. No wind = weak stems. And yes, keep that MH on 24/7 til you switch to flowering. Maybe even get a couple CFLs to put down close to the plants if they're still stretching. You can place CFLs 1-2 inches from the leaves without hurting them. Also, you can find a cheap socket for the cfls if you go to lowes or home depot and go to the isle they have the extension cords and pick up some shop lights. They're like an extension cord with a light socket & round reflector on one end. They even come with a clamp so you can clip them on to stuff to mount them.
