There are a million companies selling humic and fulvic acid products, but in reality there is little consensus on what they actually are scientifically because they are just alkaline extractions of "organic matter" which in a lot of cases is a coal like material. However, humic substances do seem to have benefits if you can obtain a good quality product. Humic an fulvic acid are carbon based bio-stimulants and their chemical structures have a propensity to act as chelators which may increase the retention of certain minerals in your medium and they may lessen the negative impacts of salt build up. These substances also are known to stimulate biology.
Ultimately there are a lot of biostimulants available and a near infinite space to experiment with different combinations.
Do not buy combo products- do a little research and investigate humic and fulvic acids with a standalone product. To be honest, there may be benefit but the research on them is done on agronomic soils and systems. Whether that applies to orchids is up for debate. If the product is just derived from 'leanoardite' its basically just coal..... long story short invest your money elsewhere for a biostimulant/boost.
If you want to tinker around and waste money....
I would put these biostimulants ahead of fulvic/humic:
Kelpak
Aloe Vera Extract
Fresh Coconut Water
Soy Amino Acids
Fish Amino Acids
Corn Steep Liquor
Impello Tribus/Continuum
EM-1
Inocucor Garden Solution
various Azospirillum brasilense products
Beuveria bassiana
