Tomato Nutrients

Hydroponic  growers measure and adjust their nutrients daily using
electroconcutivity (EC) meters, which measure the amount of fertilizer
salts in the nutrient solution.  It is similar to ppm but a more
reliable and scientific measure.  To avoid the problems of heavy
growth of foliage at the expense of fruit production a  special tomato
nutrient formulation is used which is higher in K.  Often the
formulation is changed during different stages of growth of the crop
to enhance flowering or fruit set.  Until recently, common wisdom for
tomato production was to set the EC at about 35, but current research
coming out of England recommends doubling this level for better
production and flavor.
