What's the cause of my lettuce and herb leaves turning yellow? I have a small aeroponics veggie and herb garden, recently added cilantro and catnip and within a few days a few leaves have yellow tips. Are herbs and veggies compatible in a small aeroponic garden? There's only 2 lettuce, 2 cilantro, 1 catnip, 2 basil.

There should not be any reason the plants you mention would not be compatible to grow together.
Yellowing leaves are more likely a watering issue, light or disease issue.
Since their are many different aeroponic growing systems I would check your water and nutrition levels.
