Can I Start Nutes

Hows everyone doin got a question just started my grow so far so good now my babies are three days old i transfered the roots underwater on day two they loved it i have the water balanced at around 5.5 to 5.6 now i have no nutes in the water is it to soon or can i add a lil nute oh yeah i have SUPERNATURAL VEG GROW

Hold off a while.

I am not sure with hydro but in soil I have found that holding off on nutes for atleast first 2 weeks is highly recomended. I would let them get their first true set of leaves then maybe introduce low feeding. Good luck
