I forgot to mention that I also have a bottle of chelated iron.

One teaspoon of your supplement per gallon is going to provide about 25 ppm N, 40 ppm Ca and 16 ppm Mg.

If I understand correctly, what you are saying is that the supplement that I have (calmag) is fairly weak compared to others that are commonly used in my area? Does that mean I should put more than 1 teaspoon per gallon?
I am sorry but dosing minerals isn’t my strong suit.
Are those ppm numbers for 1 teaspoon per gallon that you listed for calmag adequate for my plants every time I water? Or is that too high or too low? Should I just water with this stuff once a month? Should I maybe do a one time addition of the chelated iron to just the jasmine?
In short, I’m not quite sure what the nutritional goal should be for either the orchids or the jasmine.
