I looked at your photos. If there is a nutrient or salt problem,
it is minor. Your plants look quite healthy with only slight chlorosis. However, the container looks quite small. My dwarf citrus are in 18 inch (45 cm) redwood tubs, cylindrical and as deep as they are across. I will soon replace one tub that is rotting with a terra-cotta pot 20 inches (51 cm) across -- tapering to slightly less at the bottom -- and 17 inches (43 cm) deep. It is very similar to the pot in your IMG_3231.jpg. You need a large container so that you can keep the soil moist without it getting soggy. Too much water in the soil is as bad as the wrong pH or too many minerals. Indeed, excess water causes chlorosis. With a large container and an acidic, well draining potting mix (with acidity maintained with acidic fertilizers), any excess calcium in the water or nutrients will readily leach away. This cannot work, however, in a small container because the soil gets too soggy before proper leaching occurs. -- David E.
