    Default Potassium def or over fed?

    Hey guys . Took a view pictures of leaves and they are yellow on the outside ish . Never had it before . The ppm is 600 on one box and 250 on the box . The too plants in each box have the same issue which to me rules out over feed. Looked online at potassium def and am thinking it might be that but really not sure . Any help would be appreciated.

    It's hard to get a realistic color to decipher under that light. Perhaps a Magnesium def.?
