What's wrong with my plants?

[ligant]

Hello.
I'm growing some tropical fruit trees and shrubs in container and they look like this:






These are Bunchosia glandulifera " peanut butter fruit" or Eugenia selloi "Pitangatuba" , but most likely Bunchosia glandulifera

what's wrong with them? I don't want to lose them

Is this some kind of nutrient deficiency ?

The peanut butter fruit new leaves typically flush a very light green so this looks normal to me.

Thank you
I hope that they will survive.
