Question about shell

[Roberto79]

Hello, this is the first time that I have observed this: my partners' torts have recently developed some kind of, what I call "watermark", my question is if this is bad or appeared for a deficiency in the humidity or in some other arena? The torts are Greeks and Russians and with those I have no experience whatsoever, and due to that recent marks appearing, it indicates to me that something maybe is not being handled correctly even though the care sheets are being followed, Im attaching a picture, any help or thoughts would be greatly appreciated...

Normal. Occurs during growth.

Yes, as Baoh has said. If you look up "white, squiggly lines" in the search function, you'll see that we've talked about this before.
