Is it okay to start sowing the kohl rabi seeds now or should I wait for a couple of months and start in August? I live in suburban Sydney

Hi, my kohl rabi have failed to form the swollen tuber. They are 30cm tall and long stems, have been in the ground for 10 weeks, planted out from seedlings I raised myself and look really healthy. In raised garden bed, full sun, new soil and surrounded by successful snow peas, lettuce, broad beans and radish crops. What have I done wrong ?
