How do I figure my PPM for my MG

Don't have a clue but this is what I am thinking, please advise me right/wrong. If my MG is 24-8-16, 24% of a tsp is N, 8% is P and 16% is K. So if there are 768tsp in a gallon and I add 1tsp to a gallon, then would my N be 312.5ppm?? I am figuring 1,000,000/768=1302.0833, then .24*1302.0833=312.5ppm of N.

First, there has to be a way of figuring it out. Math solves anything. Second, I have never seen a ppm meter, but I would assume that it doesn't distinguish between every nute right? So it would just show the total ppm of everything that's in the water, correct??

yes, if you have total ppm "math solves everything" devide into percentages.... seems like a waste of time though

There somthing missing in your math there ,If you have never seen a ppm meter you should at least look at how they work, they are like 3 or 4 separate scales in ppm meters ,but they all really read the EC first before converting in to PPM reading on what scale ppm meter you have .
