You don't want to start nutrients while the coteldons are alive (the little round first leaves)

once they shrivel up and die, then you can start 1/4 strength nutrients. If the box says 1 tsp for the stage your in, use a 1/4 tsp. After a week of 1/4 strength, go to 1/2 strength, and then finally to full strength a week after that.
