Black spots on Oxheart leaves. What is this? (pictures)

FrozenFlame22 · June 13, 2013

I'm brand new to gardening and I've never been able to keep even a houseplant alive. I followed the EarthTainer instructions as close as possible given the limitations of materials in my area. So far my little tomato farm seems to be doing well. I had an aphid infestation last weekend, but an insecticidal soap took care of that.

However my Oxhearts have never really grown well. Especially the one closest to the camera. It has always been spindly and generally unhealthy looking. I don't know if this is typical to Oxheart, but I did notice that the blossoms seem really thick and irregularly shaped. There are also small knots on the vine that I don't see on any of the other varieties of tomato plants.

This morning I noticed small black spots on the leaves of the smaller Oxheart. This is only on the surface and not on the underside. The spots are not fuzzy and so far the fruit seems unaffected. The worst of the spotted leaves are pictured, but at least half the leaves on this plant have similar spotting.

The spots are also seen on the larger Oxheart, but not on the neighboring Big Beef.

The Big Beefs have some brown pitting on the underside of the fruit. The fruit is firm and doesn't appear to be rotten. Is this normal?

What are the black spots on the Oxhearts? Should I be concerned about the Big Beefs?
