The calculations are (approximately):

teaspoons/gallon (US) = 0.095 x N (from fertilizer label) for 125 ppm
N
teaspoons/gallon (US) = 0.114 x N (from fertilizer label) for 150 ppm
N

The MSU formulations were designed to be used at 125 ppm as that
provides the maximum growth without overdoing the nitrogen (which is
what the MSU folks concluded was the cause of reduction in blooming)
while providing the correct concentrations of all of the other
nutrient ions without waste.

Personally, I doubt going a bit higher on the concentration of your
solutions will have any consequences to your plants, but is a waste of
fertilizer, which can have a long-term environmental impact.

Hello Ray!

The MSU should be use at 125 ppm of N. Is it a strict number or if
you go a
little higher it would be fine too, I mean about 150 ppm?

To get 125 ppm on N, you have to use .5 teaspoon?

Thanks

Claude

| Bob,
|
| One thing you might note in your docs - Bill Argo told me that the
| fertilizers were designed to be used at 125 ppm N at every
watering.
|
| FWIW, I have been using it that way for 18 months now, and am very
| pleased.

only in

| Good luck.
