I wanted to show the pattern that nutrient deficiency creates in pothos leaves. These vines were in an aquaponic growbed, and their nutrition came from a steady supply of fish food, and the resulting nitrates from a steady amount of fish poop. After menay vines grew from this growbed, the older leave (a few months old) developed this discoloration. This is what it looks like when a plant outgrows its nutrient, as opposed to when a plant goes yellow from over watering, overfeeding etc.
