Brown stem carolina

[vrm]

Hello everyone, It's my first season in growing anything and as I love hot peppers I started a few. Meanwhile I noticed something on some of my plants and I am sure something must be wrong.

First of all those from the picture are growing well but the stem does not look right.

Both have brownish stem up to the cotyledons. One of them presents something that resembles a vertical splinter.

The other has a smaller diameter on stem below cotyledons then it has above them which seams very strange.

Could you please help me identify the problem and maybe correct it or at least how to prevent this in the future?

Thanks very much!

As pepper plants get mature, the stalk becomes "woody".
 
To me, that's what I'm seeing in your pictures.

Ok so the woody part is normal, didn t expected to show this early.

How about the splinter and the fact that as you can see in the bottom picture the stem is thinner at the base and thicker as it goes up?

Early? As we can see the plant is topped? How old is it?

Seed planted in soil 1st of February, the plant was topped just before i took the picture because I was not able to take a proper picture by myself. The picture you highlighted is the one where the stem is thinner where you highlighted.
 
It's my first time so I am just assuming that ~40 days since sowing is pretty early

Hey CD... You helped me with:
 

Factors that would be helpful currently in differentiating between sunburn and anthocyanin mutation include the uniformity of the dark coloration and whether all pods are affected, including those more shielded by the leaf canopy. Sunburn will be masked to a greater or lesser degree by mature fruit color, showing more on the lighter colored pods and less or not at all on the reds.

What do they call the

I hate that when I have something on the tip of my tongue, yet know I won't remember it until I stop thinking about it. 
 
Was it "lignification?"

Hmmm...  "Lignify" is definitely the term I'm most familiar with using - https://www.merriam-webster.com/dictionary/lignify
 
And it's the only one that's coming to me at the moment. 
 
Now I'm going stuck trying to remember another term 
 
  Give me a shout when you come up with it.
