New lithops are splitting. Others may be splitting (?) and one looks weird.

so I got these recently 1-3 had dried flowers atached and now 1 appears to be splitting right after flowering but it looks weird.

At first it was just a little wrinkled at arival with no split showing and just the dry flower. I had given it a small bit of water then right after it started doing this. I know not to water when splitting so I hope I didn't drown it. To me this one just looks weird. Is it OK? it didn't have much of a root on it or is it because of the bumps?

Is 2 and 3 also splitting or is this just how these kinds look right after flowering? 2s flowers fell off 3s still got them but they are all shriveled down in the crack. 4 and 5 had no flowers and seem to be splitting and looking normal and as I would have expected.

put another pic of 1 at the end
