Additional Info

Use all three parts of the Holland Secret 3-Part plant fertilizer together for optimal results. Using only one or two parts, like Grow and Bloom without Micro, could lead to nutrient deficiencies.

For those who do not want to spend money on a lab test, it is advisable to monitor water quality using a nutrient meter. At levels between 200 and 300 PPM, it is advisable to use Hard Water Micro, together with Calnesium, to balance out Calcium levels. Any tap water over 350 PPM should only use Hard Water Micro without Calnesium.
