They are looking good, a little info would be good, what type of light are they under? What type of
Medium are they growing in? And lastly what strains are those?
If anything I could say would be if you have the space, save the mutant, they sometimes turn into quite :beast: other wise toss it if not looking healthy, which deformed leaves sometimes has nothing to do with nothing other than genetics, I've started alot of strains where they started to look deformed but turned out beautiful!
Also, the second set of leaves look rather close (node spacing) id raise the light a bit if you have the height. Sending a :karma cloud: of a great grow!
