Necrosis, spots all over the leaf

Is this root rot or some deficiency? Help

Cal or mag issue? Whats your ph and what are you growing in?

Looks Like Coco COIR> if so it does not look like a PH issue, the plant looks healthy otherwise. If it were me I would flush with a very light nute mix, with added CalMAG or Epsom Salt, and see what that does. if its soil, I have no clue, but my first guess is always PH if it looks to be a whole plant issue, but it looks healthy, other than looking like it came out of a DR. Suess book.

I read your other postings regarding this same issue, and see many people have told you it is a calcium def, or magnesium def. have you done anything to correct this as of now? I urge you to do something ASAP, or you go from this deficiency to losing all your leafs, and fast.
