Well its hard to predict what sort of deformations will occur when a seedling has zero nutrient for a few days. Some phenotypes are hungrier than others and will suffer more, so the leaves may get a little more twisted up. As well this pheno just seems a bit different than the other, this one looks like it has narrower, more pointy leaves, while the other looks like it has wider and maybe bigger leaves. One may be taking after the mother more, while the other may look more like the father. With newer f1 genetics you can have a dozen or more phenotypes to choose from. It all depends on how long this strain has been around and how much the breeder has stabilized it. What seeds are these?
