Fire escape tomatoes in New York City --- Please help!

Hello, tomato people of Reddit! I'm new here, thank you so much for existing. Admiring all your beautiful tomatoes with envy and aspiration. Hoping you can help me with my tomato predicament ...

I live in Manhattan and a dear friend has a big beautiful garden in Brooklyn. Three or four years ago, she gave me a cherry tomato plant and I took care of it all summer on my fire escape. All I had to do was water it, and in September of that year, I harvested 36 tomatoes! It was so wonderful, it went so well.

This year I asked for plants again and she gave me an heirloom and a Pink Fang! I was so excited. June was so busy, so it took me a bit to get them in bigger pots, but by the end of that month (can't remember when, maybe mid month), they were in. Diligently been watering everyday. Weather has been so erratic this summer. Some really nice days, lots of rain, some horrible humidity, smoke from fires in Canada.

Plants have been growing well, particularly the heirloom got enormous and continues to explode. But fruit has been an issue. The heirloom has had many flowers but they are just not turning into fruit. I don't want to overwater ... I give half a wine bottle each day and test with the water meter. Surprisingly, the Pink Fang which has more fragile, less substantial leaves has made more progress. I had one fruit with blossom end root rot, and while I was wrestling with it to get the cage on, my biggest fruit fell down to the street below 🤦🏻‍♀️ So many questions. But first I guess :: I've noticed that once you pull a tomato from its stem, nothing is seeming to grow back there? So should I pull the stem off as well, so it can grow back from the limb completely? I'm so lost 🤦🏻‍♀️ I currently have four fruits coming through and I'm praying they'll be OK.

I'm on week 2 of Miracle Gro tomato food. Please send any and all tips you have for me to help these poor tomatoes grow! Just watered and today is going to be humid as hell, so thinking I should water again tonight? I don't really know what I'm doing but I'm trying my best ... I want them to grow so much! Thank you for reading xo
