Tissue turning white on hammer

[Arnav]

I have started to notice that the tissue around the new hammer buds is turning translucent and thinner - is that because the skeleton is going to grow there or is the tissue dying?

Is it turning white or is something white growing?

That is the skeleton underneath receded tissue. It doesn't look terribly unhealthy, yet. But that would be something to keep an eye on as an early indicator that it isn't thriving.
