F.Y.I. A guideline for Nutrient Limits (in PPM)

I have several friends that keep asking me what range is ok for my nitrogen, or calcium, Magnesium and so on. So maybe there is more who would like to know. This is what I have.
Nitrogen=150-1000ppm Average@250
Calcium=100-500ppm Average@200
Magnesium=50-100ppm Average@75
Phosphorus=50-100ppm Average@80
Potassium=100-400ppm Average@300
Sulfur=200-1000ppm Average@400
Copper=0.1-0.5ppm [email protected]
Boron=0.5-5.0ppm [email protected]
Iron=2.0-10ppm [email protected]
Manganese=0.5-5.0ppm [email protected]
Molybdenum=0.01-0.05ppm Avg. @0.02
Zinc=0.5-1.0ppm [email protected]

This is a Safe range, I would not deviate too far from these ranges, or deficiencies and excesses will be in your garden. I hope this can help with your garden and if it does then take a puff for me.
