Few questions and looking for any input

I just planted my sprouted seeds in their new homes. I was gonna stash em under my bed for a bit but that didn't seem safe especially with a light and my rents possibly finding my little greenhouse. So i moved it up to my little shed thing behind my house where i hang out alot. I set emm up on the floor on overflow trays, with a 27w cfl shining down on them clipped to a chair leg. The cabin is a little cool even tho it is insulated so i turned an electric heater on a low low heat setting and have it directed towards the starting pots from about a metre with a decent warm breeze blowing over them its not to hot. i watered them and...then left them to grow.

So now i come to fertilizer/feeding i was checking out plant foods in the store today, what is the best number set to use?(20-20-20) <--thats what im talking about. When do i start feeding them?and should i get a light timer right when they poke their heads outa the soil? What about molasses how would i use that to feed my plants?

thanks

The light needs to be 1 - 2 inches from the plant ( very close )
on nutes the middle number needs to be smaler in the beginning 20-10-20 and mixed 1/2 strength and used 1/2 time.

water 1 time then nutes the next time. But wait till it's well into veg stage
