Hey there, I have a Flame Tree/Royal Poinciana which I have germinated this year. While it was “cold” (less than 15 degrees Celsius for it) I kept it indoor. Afterwards, I have brought it outside (I have temperatures over 30 degrees Celsius with many hours of light). I have anorganic soil, and I use Osmocote and Biogold fertilizer. Today, I have noticed some white spots on newer leaves and brows spots on older leaves. I have a neighbour tree (black locust) which has some aphids, but I don’t see any pests on this Flame Tree. I have never had this species before, so I don’t know what I am up against. Can anyone identify the issue?
