Be careful dude, all the best in the project.

As mygirls mentioned you shouldnt be feeding them any nutes yet. Week one of the feeding schedule does not start once they have sprouted and have leaves. Week one is starts when they have 4 true sets of leaves. Before that just give them straight water.
