Water propigated root issues

[Greenie.beanie94]

I have water propergated a few plants and an avacardo seed. The roots seem to have exploded or grown something that looks like Styrofoam. I havent seen this before and i dont know what it is, im worried its a disease or is harmful as i have been having issues with other plants in soil.
Please im having trouble keeping them healthy

They’re just new roots. They will start to look like the others soon.

This is what happens to the roots when they live in water. Nothing to worry about. There does become a point I found when they need to be potted in soil.

If you check the roots on this plant in this video your see the difference for soil grown.
