If you notice a tip or edge burn often with a yellowish hue at the edge, especially on older leaves, it could be due to your tap water. To solve this, allow your tap water to stand overnight before watering so the chlorine and fluoride can evaporate. Alternatively, you can water with filtered water or rainwater. Remove any yellow leaves to keep your plant strong and growing.
As we converted this to water culture, you don't have to be concerned about overwatering or underwatering.
