Note the skeletal finger like shoots at the top. This is a tell-tale sign of malnutrition.
Nutrition can be difficult, depending on location. Know your soil, know your PH;
Macadamia trees grow best in soil with a pH between 5.5 and 6.5. They are slightly acidic soil loving plants and do not tolerate alkaline soil well. If the pH of your soil is too high (alkaline), you can lower it by adding sulfur to the soil or by planting your macadamia tree in a soil mix that is specifically formulated for acid-loving plants. If the pH of your soil is too low (acidic), you can raise it by adding lime to the soil.
It is important to regularly test the pH of your soil to ensure that it is within the optimal range for macadamia trees. You can purchase a soil pH test kit at a garden center or online, or you can send a soil sample to a soil testing laboratory for analysis. Once you know the pH of your soil, you can adjust it as needed to ensure that your macadamia tree is able to thrive.
In addition to pH, macadamia trees also have specific soil requirements in terms of drainage, fertility, and organic matter content. They prefer well-draining soil that is rich in organic matter and that has a moderate level of fertility. If your soil does not meet these requirements, you may need to amend it with compost or other organic matter and/or fertilize your tree regularly to ensure that it has the nutrients it needs to grow.
