This update is a day late and I was also late in watering this very hot week here in Brooklyn. You can see two symptoms. One there are some wilted leaves that could not recover from desiccation; two the greens are bolting or flowering/turning to seed. The first symptom is avoidable the second is not. These greens are not a hot weather crop. I will probably plant a new crop to grow a fall salad bar. There is still fresh food here however.
