Hi, this is actually a question that was posed from someone on a different forum and I said I'd ask on her behalf.
Some of her tomatoes have turned red and she was wondering if that meant they had finished growing or whether she should wait before picking them.
My belief is that once a tomato has ripened, that's it, growth-wise, but thought I'd ask the experts!

'Fraid not - once a tomato starts to ripen, that's it, even if it was under the normal size for that variety (which does tend to happen late in the season when the plants start to run out of steam.)

Which is why giant tom growers shade fruits to try and keep them growing bigger. Apparently they start to lose weight as they ripen too.

Okay, thanks. That confirms what I already thought.
