@Kiskertesz,Magnesium Deficiency Problem: A light green or yellow coloring will begin to show on the veins and edges of the lower & older leaves - this is one of the classic signs of cannabis magnesium deficiency. Cannabis magnesium deficiency - yellowing in between veins on older leavesMagnesium is a mobile nutrient, which means that the plant can move it from old leaves to new leaves. If you don't react to it promptly, a cannabis magnesium defiency can spiral out of control and cause your plant to lose a lot of lower leaves quickly. The plant will pull magnesium out of older leaves and bring them to the newer leaves. That's why a magnesium deficiency usually appears towards the bottom of the plant and on older, less important leaves. The edges of the leaves may become yellow or bright green and may start feeling crispy to the touch. This crispiness around the edges is different from nutrient burn, which does not lighten the margins inside the leaves. Sometimes you will also get light brown spotting within the margins or along the edges if the problem continues to get worse, though this may be partially other deficiencies, which often happen alongside a magnesium defiency.
