Edema or something else? (standard improved Meyer lemon)
[Los Angeles area]
My improved Meyer lemon (on a standard non-dwarfing rootstock) has been growing like gangbusters since planting a year ago. Recently, the underside of many of the leaves have started to become covered with rough brown spots. A number of the leaves fall off.
This is the only tree experiencing the issue of five trees on the same watering schedule (two blood orange, one minneola tangelo, one page mandarin, and this meyer lemon). The only difference is the others are all on semi-dwarf rootstock.
Is this edema (meaning cut back on watering) or something else (perhaps a fungal or bacterial issue)?
Top of leaves, backlit (no noticeable issues with tops of leaves, but you can see where whatever is happening is affecting the tissue)
Underside of leaves, note raised brown spots
