spring is in the air!

Last week the daytime temperatures were about 15 C so I let the seedlings get some sun on the balcony during the day.  Nights are still cold, so they were brought back inside each evening.  I have been watering with dilute fertilizer mix every time I water and that seems to have helped growth a little, although the brassicas are growing VERY slowly.  They are also quite long and falling over.  Any idea of what went wrong?  I have had them under lights since they sprouted, but perhaps they were a few inches too far away?  The lettuce looks good, and if it is warm next week, I'll harden them off and plant them.  That will free up some space under the lights for my recently sown tomatoes.
