Hello all,

About two weeks ago I planted a Charger tomato in Portland, OR in a pot. I started to notice about a week ago black edges on some of the leaves. I initially clipped the leaves off but now the remaining foliage also has black edges.

I've looked at some of the more common diseases and none of the leaves have much yellowing so I'm not sure its early blight, bacterial spot/speck. The only symptom are dry, black edges on almost all of the leaves.

Does anyone have suggestions what this might be? It hasn't been too hot here and I've watered only when the dirt knuckle deep in the pot was dry.

Any help is appreciated.
