I don't think this is a deficiency of any sort as the cut of is almost a direct line on some of the leaves. I believe this is one of two things. The better of the two is called Variegation, its caused by genetics and is known to not be a useful trait in cannabis, they need the leaves to make engery and grow and if over 50% of the leaf is lacking green its not efficient at producing energy or using the lights. - The lesser of the two is TMV or Tobacco mosaic Virus, its not good and is contagious to other plants. I would cull the plant and separate it from any others then use a bleach spray and clean the entire area. Everything used that touched the plant "tools, containers, strings, should be bleached. The medium should be tossed out unless you can sterilize it somehow. Variegation makes them look pretty and a lot of ornamental plants have this characteristic for this very purpose, to look pretty :D But the virus is not fun. IMO there is nothing you can do about this, let it grow out or kill it.
