Plants growing in water need to be fed. When grown in soil, nutrients dissolve from the soil and are absorbed. Regular plant food for soil-grown plants won't work as well as special hydroponic food. Regular fertilizers don't contain all nutrients because the soil also supplies nutrients. That said, pale leaves often indicate lack of nitrogen.

Fertilizer needed.

Why are you growing in water...that's not normal for plants, unless they are pond or marsh plants.

You might add a little Epsom salts (2 Tbsp to the gallon) to the water. It helps with the chlorophyll, which gives plants their green. Also, you might consider more light for it.

Add dirt that they will need to grow in if the root system has started.

These plants need to be potted in compost to get the food they require.
