@Rowdy_extracts, If this is the only one of 12 that is showing any deformities of this nature, then it could well be the individual seed - genetic abnormalities like what I am appearing to see above are not that uncommon in plants. Personally, I’d continue to grow it as usual as the plant may do just fine. About the only thing that I would not do would be to use this plant for seed stock.
