What state are you located in, how big are your torts, how long have you had your torts, are they kept inside or outside, are they kept warm and humid enough, We need a little more info and history to help you
May we see a pic of each of them, especially the two you are concerned with? A pic of each of their faces and a pic of them from the side (whole tort from the side)....
As stated by others, we need more information! Enclosure specs (indoor or outdoor), lighting / heating arrangment, temperature readings (ambient daytime, ambient nightime, basking and cool side), substrate, humidity levels.
