Revisa las dosis de nutrientes ya que no están siendo suficientes, ahora si no haz comenzado a fertilizar ya es hora de comenzar con pequeñas dosis 💪

I have not amended at all. I guess I need to start adding nitrogen? I will do more research and then start small.

Sie hat ihre ersten beiden echten Blätter hervorgebracht, die eine Krankheit zeigen,aber es könnte sich auch um eine Pilzinfektion oder Schimmel handeln, der die Pflanze befällt. Was meint ihr was es ist? überlebt sie es?

Seeing some top bud leaf discoloration
Starting to see small dark/black discolorations on the leaves. Since I don't know the genetics, I can't tell if it's prone to dark leaves. Could it be signs of anything else? Note: Started watering only using TopMax and ActiVera because of some possible Nitrogen toxicity
