Don't know if this is the correct place to post this but I grow hydroponically and soil growers don't use high ppm's. I read a lot of posts that indicate a lot of people use a very high ppm nutrient solution - some as high as 1800 ppm. Can a plant utilize all of the nutrients in a solution with 1800 ppm? Or is it just a waste of nutrients? I know that some plants can tolerate very high ppm's and grow well - but is it necessary to be that high? Would they grow just as well with a nute solution of say 1000 ppm's?
