After several discussions and questioning with different nurserymans (not in big market plant) I am on the conclusion that 0.5 gr/L of fertlyser at each watering is the most usual mode of distribution applied.

Are these slipper orchids yur talking about?
Do you know how may PPMs total that is?
I think you will find that 0.5 gr/L is basically the normal standard for MSU type formulas.
THe answer to the question is simply-water.
A lot.

1 gram is 1000mg if in one L ==1000mg/L or ppm
So 1/2 gram = 500ppm.
That does not account for waters of hydration for any of the individual salts.
Yes.... 500ppm total fertilizer salts.
Then MSU at 13% Nitrogen gives a fertilizer with 65 ppm nitrogen.
Correct or not?

About right.
And should also be about 1/2 tsp/gal. Although volume/weight of dry salts is somewhat off from volume/weight of water. So I think 1/2 tsp/gal MSU usually comes out closer to 80ppm N.
If this question is related to the quantities of fertiliser used by professional paphs grower I say: Yes
Yes this is correct! 13% N is the Nitrogen content of the fertiliser as it is. This is the value measured on a dry sample but not on a full dehydrated sample (with salt molecules having lost their water constitution) .

In the detox department, I guess dihydrogen monoxide is more appropriate.
