Liquid phosphor fertiliser
Since ages, phosphor has been known for its role as activator of root activitity and blooming of plants. Phosphor also plays a role in the forming of cell membranes and it is a molecular building block for DNA and the energy carriers ATP and ADP. A deficiency of phosphor manifests itself in a slow growth and purple discolorisation of the nerves at the lower surface of the leaf and purple stems caused by an anthocyan-accumulation.
In order to stimulate root development and/or flowering add 25-100 ml. per 100 liters of nutrient solution as an addition to other fertilizers. Beware: a too high a dosage might influence the absorption of other nutrients.
