I would keep all the leafy stuff going, lettuce, kale or whatever. Keep the radishes going. And the cucumbers. Forget the tomatoes because i doubt that you have enough time left in the season for them to grow bid enough to make fruit.
Just as a point of information, my tomatoes are in a 20" wide by16" deep containers and there are 3 plants. I
planted them as seedlings from Lowe's in mid May. The containers have several drainage holes and I use Miracle Grow potting soil. Just plain Miracle Grow. NOT the moisture retention soil. NOT the type with slow release fertilizer! Just plain Miracle Grow.
