Too early for nutes mate! What kind of grow medium are you using? Is it an enriched with nutes soil? You don't need to add any nutes, specially if your soil is enriched!! Flush it with just water, let it drain and when dry continue your watering schedule. Nutes will be needed at about three weeks depending on strain... If you decide to feed it nutes go with 1/4 of suggested dossage and move on to 1/3, 1/2, 1/1 week after week!
