Aquarium plants can turn brown or gray due to a variety of reasons, including inadequate lighting, poor water quality, lack of nutrients, or algae growth. Insufficient lighting can cause plants to lose their green color and appear brown or gray. Poor water quality, such as high levels of ammonia or nitrites, can also stress plants and cause them to discolor. Additionally, a lack of essential nutrients, such as iron or potassium, can lead to plant deterioration. Finally, algae growth on the plants can also cause them to appear brown or gray. Regular maintenance, proper lighting, and nutrient supplementation can help prevent discoloration in aquarium plants. **
