Blossom End Rot. Sometimes unavoidable on the first few tomatoes. Sometimes indicative of other problems.

Looks like Blossom End Rot.
1. What are you feeding the plant with?
2. What type of soil are you using?
3. What is your watering process?

Calcium deficiency

Blossom end rot.
Caused by calcium deficiency. I use calcium salts in a product called “bonide rot stop”. It comes as a liquid.

Blossom end rot, while technically caused by calcium deficiency, is often NOT because the soil lacks calium, but because other reasons prevent enough calcium from reaching the fruit. As another person commented, often the first few fruit of a plant have BER, and then it just improves on its own with no action on our part and the fruit from the majority of the season is fine. Or supposedly erratic watering can cause BER.

You need to disolve calcium in water and then spray the plant. Calcium moves too slow for root fertilization.

BER.

A bottle of cal – mag will straighten that right out

Are you growing under LED lights? If so cut it open and see if the black bit is firm and also on the inside, too. If so, this is a weird thing that happens from lack of UV light. I had it happen with my micro dwarfs and as soon as I added a fluorescent light successive fruit were just fine.
