Yellow Tomato Plant Leaves

Anonymous added on February 4, 2011 | Answered

I am a Family & Consumer Science teacher growing tomatoes, lettuce, basil, beans, and parsley from seeds in an aeroponics unit in my classroom. We are misting the roots with nutrients, but the little tomato plant leaves are turning yellow and the basil bright dark green. I think the nutrients need to be changed-using 5-7-5. Do they need nitrogen? No one could help answer this.

It is a nutrient imbalance. They do need nitrogen to produce foliage, so yes, adding more nitrogen will probably help them do better.
