Are these nasturtiums diseased?

[Precarious]

I started these nasturtiums from seed and when they very first popped up they were this colour but others were the normal green and I maybe just assumed it was different but I couldn't find any that looked like it so was wondering if they were diseases or something

They might be a different variety. I had some dark burgundy colored ones that had the darker leaves.
