Nope, no clones grown from seed and two strains. I'm actually using coco medium with coco specific hydroponic nutes. I guess I could try a foliar spray also. TyI go with genetics, if they are clones. I have had weird leaves from a couple of plants, but not 3 or four in the same group. If not clones, no overheat, standard soil and nutes, then it might be a mineral def, but very rare in an outdoor grow. I would use a foliar spray with a seaweed base ( Maxicrop) for added minerals, but after that, all the bases should be covered. Good luck
