I have a Lemon sprout (Aprox 2 months old) that is getting tiny yellow dots on its leaves.
3 days ago I have move them from indoor climate to outdoor climate (Dallas TX). Soil is moisturized. (No direct sunlight). Temperatures around 90F

The affected leaves are the first 4 leaves the it gets when it sprouts.

Thanks in advance!

Hi two of my apple sprouts have a leaf like the one in the image attached to this topic. Does anyone know what is going on? I am new with apple trees.

Does anyone know how to get rid of it?

Thanks in advance!
