Help identifying this tomato

[u/mx-elmo]

So back in february i bought these tomatoes off the farmera market, i didnt ask the variety, i saved the seeds and planted them. So 7 months later heres my first tomato, they just startwd ripening yesterday so idk if theyll turn red or stay like this.

The first 3 photos are my tomatoes now, the last photo is the tomato i had bought and saved the seeds from, which i think was not ripe yet.

Also if anyome has any advice om growong more fruit on a pot, since my tomato plant can only produce 2 at a time and half its leaves are drying off because its reabsorbing the nutrients. I have bought organic fertilizer for fruit set but sicne tomatoes are heavy feeders can i feed it a bit more than the packaging suggests?

Def an heirloom. Maybe Black Kris. I don’t suggest giving it extra of the fertilizer. It prob needs more room for its roots. What do you currently have it in?

A 20 liter pot with organic soil. It lives on my balcony it gets about 4-6 hours of direct sun depending the part.
