Combination of Manganese, Potassium and Trace Minerals for bright green colored aquatic plants.
Potassium deficiency leads to yellowing of leaves, especially at leaf edges & common in younger leaves. Also develops dead or yellow patches on leaves.
Manganese deficiency leads to yellow spots and elongated holes between plant veins.
Regular use of RO water also cause depletion of macro minerals such as magnesium and calcium. Application of K++ replenish these minerals required for plant growth.
K++ limit the algae growth as it has no nitrogen or phosphorus residue.
