In hydroponics, the nutrients are the soil. Get them right and your plants grow like mad. Get them wrong and you'll see it in the leaves within days! Here are all my guides on hydroponic nutrients, from picking a fertiliser and mixing it up to keeping pH and EC in check, spotting deficiencies and flushing before harvest. New to feeding plants in water? Start with the beginners guide. There are two calculators in this section too: an EC to ppm converter on the pH and EC page, and a nutrient dose calculator on the nutrient management page.
