Apple seedling turning reddish?

What's going on?

Usually when this happens to young seedlings it is because of improper nutrition or a lack of oxygen. In apples young seedlings and immature trees need a little more nitrogen than fully mature trees. It is doubtful it is an oxygen issue but it won't hurt anything to assume that it is and treat accordingly. To treat this put a cup or two of hydrogen peroxide into a gallon of water and pour around base of plant. This will aerate the soil loosen it up.

Thanks Chuck. Thing is, I have another seedling of the exact same size in the exact same type of soil that's completely fine. Down right peculiar.

Well, think of it this way. If these "seedlings" were cuttings they would have identical DNA correct? But the seeds that sprouted these seedlings have slightly different DNA. So the two plants are not the same, genetically speaking, and therefore their growth habits and needs will probably be slightly different.
