Good morning! I am the coordinator for a community garden. One of our gardeners has a tomato plant that has new growth changing color and shriveling. We have not seen this before and are reaching out to you for possible help. Our garden is organic and chemical pesticide free. The water we use is donated by the city and comes directly by hose. The other tomato plants, about a dozen, are healthy and doing fine. All plants were purchased from a local nursery. Thank you so much for your help!
