tip roll, pale spots on tomato seedling leaves
My tomatoes are 5 weeks old, generally fast-growing and healthy-looking. Ever since I started putting them outside on warm days (over 50; in a sunny spot, slightly sheltered but still gets wind), a few leaves have rolled at the tips. I figured it was just stress. Today I found this spotted leaf (oldest true leaf on its plant) with a rolled tip and began to wonder if I was actually dealing with a disease (powdery mildew? I know the kale in the greenhouse had that months ago, but I thought it was species-specific....gray spot? bacterial spot?) A couple of other plants had older leaves with whitish tips. I've attached the spot pic; I think maybe you can see bigger pix of the spot and the white tip here:
Any ideas greatly appreciated.
