worm castings for sprouts?

[newbie01]

Well I started germing about 8 seeds a couple days ago and they are about to sprout and I am going to put them in cups for the first days until they sprout or so and then im going to put them outside a bit later because its been raining for days here. My main question is, since i have nightcrawlers in captivity if I could use a light mix of casting tea for the young sprouts when I put them in the ground as to give them a kick start because its a little late. Its been raining for the past 15 days or so.
