What are the causes and solutions for white spots on aquarium plants?

White spots on aquarium plants are typically caused by a fungal or bacterial infection, nutrient deficiencies, or poor water quality. To address this issue, you can try treating the plants with an antifungal or antibacterial solution, ensuring proper nutrient levels in the water, and maintaining good water quality through regular water changes and proper filtration. Additionally, quarantining affected plants can help prevent the spread of the infection to other plants in the aquarium.
