Hi all, a couple of months ago, I bought a young Cogshall Mango tree that I have kept in a container in the yard. I live in Florida and we have also had a lot of summer rain here. It is about 3 feet tall at the moment. It has access to full sun and is in a soil that is meant for good drainage. The tree had some dark spots on it when purchased. Recently I have noticed that the some of the younger leaves are starting to discolor, black dots are found on the leaves, and on a couple of the leaves, you can see a small clear strand extend from the underside of the leaf with a white dot attached to it. I think I may have some sort of pest infestation brewing, but I have no clue what kind of pest or what multiple PESTS are affecting the tree and how to combat them. I also think it could be something fungal happening at the same time with all the summer rain we have, but I'm trying to figure out the pest situation. I have tried to research the cause, but I am bombarded with information and it's overwhelming. Spider mites? Leaf miners? Fly larva? Can anyone take a look at the photos and please try to identify the issues with my young tree? I don't want to lose it without a fight! Thank you!
