If a large portion of the soil is dry, it may indicate that the roots are not receiving enough water. Dryness can cause brown spots to appear on the leaves, which start at the edges and make the leaves curl. The plant may also look wilted or dry, and the soil may recede from the pot, preventing water from reaching the root mass. To remedy this, mist your fiddle leaf regularly to increase the humidity around the plant, which can help it recover.

It's important to ensure that you're not underwatering your fiddle leaf fig. A regular watering schedule is recommended, where you water the plant when the topsoil is dry. If you unintentionally let the soil dry out completely, you might notice that the branches become limp and the leaves droop and dry up.

Another helpful tip is to increase humidity levels by misting the leaves of the plant regularly.

To maintain the health of these plants, it is important to keep them away from serious pest or disease issues, such as spider mites, scale insects, and bacterial or fungal diseases. These issues can cause leaf damage, such as spots or dark patches, as well as small bugs on the leaves.

If you notice any of these symptoms, treat the issue as soon as possible with an appropriate fungicide, pesticide, or other remedy. Also, ensure that your plant has sufficient air circulation and is not sitting in overly damp conditions, which can help prevent future problems.
