Hi Daniel,

There are meally bug present which can be controlled with PestOil which should be applied now. Alternatively, try Yates Nature's Way Citrus & Ornamental Spray. Next Winter when the tree is dormant an application of Lime Sulfur will help remove any pests such as scale and meally bug which will he hiding in the bark. To help inprove the trees health you could apply some Yates Uplift root booster or Yates Seaweed booster. The trees appear to be quite stressed and this may be due to the shady conditions.
