Dark Lesions on Stem

Was wondering if anyone could identify what may be causing these dark lesions on my overwintering peppers' stems...

The new growth appears healthy, the plants are flowering again. I believe these lesions are some kind of infection that may have entered through the cuts I made, though I tried keeping everything sterile.

It was spreading on one plant, though it does not appear to be on the others. Strangely, the best new growth was above the spreading lesions. Cut off the branches on which it was spreading and sealed cuts with wax.

Should I be concerned?

The symptoms don't exactly match, but it may well be phytophthora blight, simply I am not seeing a full-blown infection due to the low temps and dry air (they're sitting on a windowsill with below freezing outside).

Just to clarify, it's on all the plants, but the lesions were spreading on only one.
