Determining nutrient component PPM of used nutrient solution?

How would one determine the amount of individual nutrients used while replacing a reservoir of nutrient solution? If i had a detailed list of the PPM of the different nutrient components while mixing the nutrient solution together, how would that help me determine how much of each nutrient my tomato plant is using? Would I have to submit a sample to a lab? Is there a tool for home analysis?
