This is something I haven't read before, an interesting tip for supplying some nutrients.
The entire short article by Dr. James E. Faust contains some nice tips and real information based on practice. An interesting read.

Unrooted cuttings arrive with a finite supply of nutrients in their tissues. These nutrients rapidly disappear in the first week of propagation as overhead mist is continually applied. Therefore, it’s expedient to apply nutrients prior to root initiation. There are different methods to deliver nutrients, but the use of water-soluble fertilizers in the mist solution has become popular over the past decade. The nitrogen concentration usually ranges from 50 to 100 ppm and the macronutrients are provided in proportion with the nitrogen. The minor nutrients are provided in proportion to the iron concentration, which is typically 1 ppm. Thus, the macros and minors should be mixed independently or a special propagation fertilizer can be purchased.

the water should have a low electrical conductivity and a low alkalinity (low concentration of bicarbonates). When mist is frequently applied to leaf surfaces and is constantly evaporating from those surfaces, salts contained in the water don’t evaporate and leave residues on the foliage.
