The optimum temperature for cabbage growth is 60º to 65ºF (15 to 18ºC). Often, the problem is temperature—too high or too low. Cabbage also needs even moisture supply during head formation. If your plant hasn’t bolted yet, it may eventually form heads. If they do start to flower and bolt, pull them up and try in the fall when the weather is cooler (for most areas). Good luck!
