 Gradually increase the nutrient strength during each cycle ie, start on 1.5mS during the Vegetative growth stage and gradually increase it to 2.0mS towards the end of the stage,
 DO NOT IGNORE pH. Certain minerals can become inaccessible to the plant when the pH of the solution is outside the recommended range. If using a pH Test Kit, aim for ‘6’.

Both Grow and Bloom have an ‘A’ part and a ‘B’ part. These must be added in equal amounts as per instructions to maintain the ideal nutrient profile for the plant.
 Re-circulated nutrient tanks should ideally be changed once a week in order to maintain the optimum mineral nutrient profile in the tank.
