Default Re: Plant Deficiency Picture Diagram

Magnesium deficiency is characterized by very dark green leaf veins and some kind of discoloration in the tissue between veins. The exact color depends on the plant in question, so clear leaf tissue is possible.

Clear leaves sounds like a lack of light to me, but it depends where the problem shows up on the plant and could be something different entirely.
