| sharyn here is my fertilizer from MSU 13-3-15-8Ca-2Mg for pure water (reverse osmosis and rain water)
here is thier other one MSU 19-4-23 for tap water *(Ideal for the Northeast region Well or Municipal water supplies)
instructions
--------------------------------------------------------------------------------
MSU fertilizer was formulated at Michigan State University with the help of PhD Bill Argo of the Blackmore Company. The closest to nutritionally complete of any orchid fertilizer on the market.#

MSU 13-3-15-8Ca-2Mg for pure water (reverse osmosis and rain water)
Formulated for a regime of constant feeding.
Depending on you growing conditions a nitrogen PPM of 100 to 150 is a good starting point. This will satisfy most nutrition requirements safely for growing in slightly less than ideal growing conditions i.e. lower light or temperature.
To achieve this a slightly heaping 1/2 teaspoon and a full teaspoon of MSU per gallon produced the following analysis:
.6 tsp
103 ppm - nitrogen
10 ppm - phosphorus
99 ppm - potassium
For a TDS of 177ppm per gallon.
1 tsp.
172 ppm - nitrogen
17 ppm - phosphorus
164 ppm - potassium
For a TDS of 353ppm per gallon.
If your growing conditions are ideal you may wish to MAX OUT your nutrition at 250ppm.
1.5 tsp. or MSU produce the following analysis:
257 ppm - nitrogen
26 ppm - phosphorus
126 ppm - potassium
For a TDS of 529ppm per gallon
