my auto has been doing great since I planted it from seed. It's a little over 3 weeks since it sprouted and just overnight started to show pistils. Later on after checking them again they've started to develop brown tips. Could this be from a nute def? I haven't used nutes yet since I'm using fox farms ocean floor but I did start some veg nutes today when I watered it. Should I be worried? my lights are about 2' from the top of the plant and it did suffer from some minor light/stress as the leaves were slightly curled up like a taco but they've since uncurled.
