I am doing an experiment for a major essay where I have altered the pH
levels of the nutrient solution for the hydroponic plants. I am growing
marigolds, in the range of pH 5.5-8.0. I know that some nutrient
deficiency has occured as chlorsis has occurred on the young leaves of
some of the plants, and there is a large range between the tallest and
shortest plant, however I cannot seem to find much research on which pH
levels affect which nutrients.
I would really appreciate it if some one could provide me with some
insight on this.
