Dont panic-yet!
Are there signs that the plants are forming a seed head?, ie a single central stem.
Expect a good crop to get to maybe 50cm, on a ‘football’ of perhaps 25cm. Bolted ones are of little use, except you can use them for flavour in soup perhaps, discarding the wood by straining. Of course, the foliage can also be used if appertising, for the same purpose. Extra mulch may help.
