You can do away with those 2 upper lights (soft whites) you can get just use one bulb really until you develop some more leaves. With cfl's start small and add as you go. and the stem is fine just has to do with strain if you do anything wrong at this stage it will just die they are fragile that small and don't need any nutes other than whats in the soil already.
