This is my first year as a gardener. I'm growing tomatoes in my greenhouse. The ones in pots are doing brilliantly  ( I think) but the ones in grow bags are not flowering very much at all. They are about 3ft tall.  At this stage is it too late to transfer the plants from the grow bag into individual pots?

You should get away with it - remove them with as much soil attached to the rootball as you can, and plant them deeper in the pots than they are are in the growbags (not difficult - there are some woefully skinny growbags out there!) This well help develop more roots to assist their recovery.

Probably best not to attempt this during the heat of the day at the moment!

As already said you could replant them in a deep pot. I would plant them as deep as possible as they will send out new roots from the buried stem and should do better.

Alternatively could you take the bottom out of a pot,I use flower buckets from the supermarket & drop it over the top of the plant, down to the compost in the grow bag & fill up with more compost, as previously said tge plants will grow more roots, you’ll need to remove the leaves below the compost level. Then when fruits have set, feed from the top of the pot & water at the bottom & youll have successfully done some as ring culture plants
