Outdoor Marijuana Crops and Iron

Iron deficiencies in the outdoor marijuana crop will be pronounced in chlorosis in the younger leaves of the plant. There can be yellowing of the leaves that will be between the veins that will begin with the lower and middle leaves of the outdoor marijuana plant.

It is possible to correct this situation by adding an iron supplement to the water and use it on the plants. This is important because the missing mineral or deficiency can inhibit the growth of the plant can cause it to lose the leaves and the harvest. The mineral is difficult for the plant to absorb if the ground where the outside marijuana crop is located is too wet.
