Common Leaf Issues in Romanesco
Discoloration and Yellowing
Yellowing leaves are often a sign of nutrient deficiencies, overwatering, or poor soil drainage. It can also indicate the presence of pests or diseases.
Spots and Blotches
Dark spots or blotches on the leaves may be caused by fungal infections such as downy mildew or bacterial leaf spot. These can spread quickly if not treated promptly.
