Fatsia - rust, pests or deficiency?
Hello All,
Im trying to work out whats going on with my fatsia.
It has grown over the last two years or so since planting.
It suffered from pests the first year but recovered.
Now its covered in the yellow mottle pattern seen below. Is this rust or something else? It is in a brick raised bed so the soil may be slightly shallow but the pattern doesn't seem to match deficiency photos I've seen. It's mostly in shade and is kept relatively moist most of the year.
Any advice would be lovely. Thank you.

Feeding is rarely a cure for a plant issue. Perhaps, though, an application of sequestered iron might not do any harm. You can do the iron and the seaweed in one product.
