it's my understanding it needs a certain amount of clay particle's suspended in the solution to be effective.

I actually had a talk with the horticultural guy (has some sort of degree if that means anything) at my hydro store about this topic specifically. It's my understanding through his opinion that alot of nutrient companies don't even know the proper dosing for these. Specifically when to use them. For example I use GH Flora, and in their nute schedule they say diamond nectar during veg. The bottle says its humic acid which is good for veg, however guy says this is actually fulvic acid and is suited for flowering. He brought this infomation to the attention of the General Hydroponics rep specifically, who had no answer for him, though didn't disagree with the logic. He did try to explain the difference to me, however I found it somewhat confusing, but he definitely mentioned this specifically which I also found quoted in the Humic acid wikipedia: "fulvic acids are humic acids of lower molecular weight and higher oxygen content than other humic acids."

With that in mind what I took away from my conversation with him is that humic and fulvic acids are beneficial, however you have to know whats really in it, and not necessarily follow the schedule as described by the manufactuer. Humic acid is suited for the Early stages of growth, and Fulvic for the later stages such as during flowering.

With that in mind, Diamond Nectar is the only item in the GH feeding schedule I don't use, but I do use a 3rd party humic acid that I also got as a free sample. Not sure what I plan to do if anything in this regard when the sample runs out. I keep my nutrient feeding schedule the same, and mess around with suppliments. Not sure if its helping, but doesn't seem to be hurting. I beleive these chemical compounds are supposed to help the plant absorb nutrients in general.

You are confused about some stuff.
There is humic acid and then there is fulvic acid.
GH cannot label anything as fulvic in California, so they call it "low molecular weight humic acids" which is probably not a lie... They are very similar compounds..
In any event, humic is not better for veg than flower any the same is true for fulvic.
Fulvic acid is helpful because it acts as food for benefical microbes and is a chelating agent - it combines with your soil and hooks to molecules of nutrients and binds to them and makes 'em more available to your plants.

The only "rule" I know about the two is that you use fulvic for soil and hydro but only use humic for soil.

peace out

AN had their Humic product says its fine for hydro http://www.advancednutrients.com/hydroponics/products/grandma_enggy_H2/grandma_enggy_H2_product_information.php

Thanks for the link.. Yeah, I thought I read that studies showed that humic acid did not help in straight-up hydroponics WITHOUT any organics or microbes...

Here is a great article that describes Fulvic and Humic acids which are basically the same thing but at different atomic weights - so from the same stuff but different in their effects.
