Why does my tomato look weird?
There are several factors that cause misshapen fruit, but the most likely cause is low temperature. Tomato fruit will develop the best shape if the temperature is above the mid-60s. Lower temperatures cause ridged fruit (a bumpy shoulder) and catfacing (ugly bottom of fruit; see below).
Why are my tomatoes discolored?

Why are my tomatoes not turning completely red?
When temperatures exceed 85 to 90 F, the ripening process slows significantly or even stops.

Why are my cherry tomatoes discolored?

What does tomato blight look like?
There are a few signs to look out for when trying to spot blight on your tomato plants. It will cause leaves to shrivel and turn brown. It also causes brown lesions on the leaf stalks, and the plant stems. Blight symptoms on fruit will appear as sunken areas which turn brown.

Why are my tomatoes gnarly?
“Catfacing” is when fruits develop scarred, malformed or “gnarly” growth. Most often, it comes from too-cold temperatures when the young fruits were first developing. (Tomatoes don’t “set” fruit well at all below 55 degrees.) Again, some varieties are more prone to this growth malady than others.
