well have not added anything, just letting them go, the white areas are turning brown and dying, (mostly the new small leaves and tips of the new suckers, main stems) but the older bigger leaves are green, firm as if they are not lacking water, but heavily wilted, especially the Cherokee purple. I don't know whats wrong with them, gonna let them go though, I have 18 plants in the ground that are doing ok, including a Cherokee green with about 10 tomatoes on it now so I can afford to lose the box I suppose
