General use

0.5 to 1ml per litreThe required dose depends on the quality of the water, the EC and the type of substrate. Usually the ideal pH for plants is between 5.4 and 6.5. For fast-growing plants, to improve the assimilation of Nitrogen (N) during the growing period, a pH of 5.6 is preferable. During flowering, to encourage the absorption of Phosphorous (P) and Potassium (K), adjust the solution to a pH of about 6.0-6.2.


3Acid down can also be used after cultivation to clean and eliminate waste and accumulations of salts in hydroponics systems.- Apply the product undiluted by soaking the elements as necessary and leave for 24 hours. - Rinse thoroughly.
