4. Fertilizer yellowing, which means too much fertilizer, manifested by yellowing and falling off of the old leaf tips, while the new leaves are thick and glossy but generally not comfortable and flat.
5. Drought yellowing, caused by long-term lack of watering or dehydration, the lower leaves gradually turn yellow and fall off, aging.
6. Alkali yellowing, especially some southern flowers that prefer acidic soil, while northern water is alkaline, causing leaves to fade and turn yellow or even fall off.
7. If the orchid leaves are yellowish but growing normally, it may be due to excessive sunlight.
8. If the orchid leaves turn yellow and the new buds are small, it is due to excessive sunlight, lack of nitrogen fertilizer, and necessary humidity.
