Hi guys,
I recently purchased a meyer lemon tree and it was doing well until this week when the leaves began to turn yellow. The yellowing appeared punched out and appears more prominent on the sides. I am not sure what can cause this. My soil humidity level is ok, I'm using parrot which helps to prevent over watering. I've attached few photos. Any help is highly appreciated. I really don't want this plant to die.
Thank you so much
DS
