Answer: The tomatoes will ripen when they get enough heat and sunshine, so make sure your plants are getting plenty of sun. Although the pots are small, the summer is nearly over and plant growth will slow from now on so I don't think they need to be repotted. Next time, though, start with larger pots for your tomatoes. Yellowing leaves at the bottom of the plant are normal for this time of year. Pull them off if they look unattractive. Once your plants get the sunshine they crave, the fruits should ripen.
Enjoy your harvest!
