Broad beans - flowering early?

My broad beans have started to flower. They otherwise appear healthy and are growing up fast in this weather. But they are not the dwarf variety and are currently only about 6-8 inches tall. Should I be concerned that they have started flowering? Or is that to be expected? And if something has gone wrong is it too late to correct?

 

You're fine... go with it.. broad beans are tough!

It's not to late to sow another batch for a later crop... not too warm, or even outside
