If you want to make the rich and the rich greener, you need to make their nutrient absorption level more balanced. The nutrient absorption of hydroponic plants is relatively worse than that of soil culture.

Among the supplementary nutrients, if you want its leaves to be greener and stronger, you can slightly improve the nitrogen level in the fertilizer.
Another is that some iron chelating agents can be added to the water, so that the water cultured Lucky Bamboo can better absorb iron ions, so that its leaves will become darker and greener.
