Never nute a stressed cloneling.

After transplanting into soil, the roots need to adjust. Ease-up on the fan action, raise the lights a tad, and treat them like unrooted clones till established. (provide a humid enviornment)

Do not keep soil soaking, and don't keep spraying the leaves. This will cause mold, mildew, and possible root rot. Best to spray the dome or cover...or whatever you are using to keep the humidity levels up.
