Probably your turnips are past their prime. Root crops eventually get woody. Plant more now for a fall crop.

As I understand it, root veggies get more woody in the high summer heat as well. That's why they're typically grown in the spring and fall. Spring Turnips should have been harvested by now and fall turnips aren't ready to plant yet...maybe in the coolest zones you could plant seeds now... Check your local Agricultural Extension or the one nearest you for exact planting dates.

I really like "Just Right Hybrid". It is more tolerant of cold weather than many other turnips, but it is not recommended for spring planting. I tried it once. Didn't work out at all. The catalog I got it from also says it is for fall planting only. It should mature in cool weather.

Timing could be tricky in Ontario. In my experience, this variety doesn't make cute little "baby turnips" if you get the timing wrong and nasty weather threatens. Roots stay skinny until the tops are really big. Tops are good though. Mild, hairless. Tough midrib.

I don't think it is 100% turnip. I think it has some other brassica in its background.

At 60 or 70 days, depending on the weather, you should have a big, thick-skinned turnip that is tender and sweet. Not the prettiest to look at, as there are roots hanging from the bulb. They hold in the ground much better than most turnips as the weather turns cold (for California) or rainy, but I don't think they're as cold hardy as, say, kale.
