Is this happening to just your radishes, or is it happening to other root vegetables too? I have never grown radishes but I have had this issue with beets and carrots and found out the hard way that a lot of newer subdivisions will scoop off most of the top soil and only leave a little bit before you hit clay. The lack of soil prevents things like root vegetables from growing larger. If you know that’s not an issue, then it’s probably something else.
Well then it sounds like that’s not it. Could maybe also be a nutrient issue. Some of the larger vegetables tend not to grow as big when there’s a lack of specific nutrients like calcium. But again, I’ve never grown radishes so I don’t exactly know what they need.

I have them in a pot about 15" deep with soil. I planted them in the top 0.25".

They maybe overcrowded.
