[font=arial, helvetica, sans-serif]an explanation of n-p-k[/font]
[font=arial, helvetica, sans-serif]
ok, so your confused. On some nutrients the npk seems low, like 2-1-3. And on others it can be high, 14-24-16. Whats the deal here?[/font]
[font=arial, helvetica, sans-serif]
nutrient values (n-p-k)are expressed as total percentage of weight as packaged. Organic nutrients typically tend to have lower npk values than chemical nutrients. Don't let this fool you, you can easily burn plants if you overfertilize! [/font]
[font=arial, helvetica, sans-serif]
powder nutrients tend to have higher npk values than liquid nutrients because they are not already partially diluted with water. Do not let low n-p-k values fool you, what really matters is how strong these nutrients are when diluted to recommended levels ie: Thier tds/ppm/ms/ec/cf. For example superveg will give you a tds of around 1000 ppm when used according to directions, while aquafeed "v" powder will have a tds of around 600 ppm if used as recommended. [/font]

what does n-p-k stand for?[/font]
n = nitrogen 7-9-5
nitrogen is the first major element responsible for the vegetative growth of plants above ground. With a good supply, plants grow sturdily and mature rapidly, with rich, dark green foliage.
p = phosphorus 7-9-5
the second major element in plant nutrition, phosphorus is essential for healthy growth, strong roots, fruit and flower development, and greater resistance to disease.
k = potassium (potash) 7-9-5 the third major plant nutrient, potassium oxide is essential for the development of strong plants. It helps plants to resist diseases, protects them from the cold and protects during dry weather by preventing excessive water loss.
