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

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
