I find it in the 《Cultivating Exceptional Cannabis -DJ-Short》
BTW,DB‘s guidance on the flush is already very awesome for me

I would think that some high quality humics could further consume any traces of minerals that remain, that's what I'm shooting for, and enhance flavors and terpene profiles. The heavy-metal binding abilities of humic acids have been exploited to develop remediation technologies for removing heavy metals from waste water.
A typical humic substance is a mixture of many molecules, some of which are based on a motif of
aromatic nuclei with
phenolic and
carboxylic substituents. The functional groups that contribute most to surface charge and reactivity of humic substances are phenolic and carboxylic groups. Humic acids behave as mixtures of dibasic acids, with a
pK1 value around 4 for
protonation of carboxyl groups and around 8 for protonation of phenolate groups. pK values for a given sample are average values relating to the constituent species. The other important characteristic is
charge density. The molecules may form a supramolecular structure held together by
non-covalent forces, such as
van der Waals force,
π-π, and CH-π bonds.
The presence of carboxylate and phenolate groups gives the humic acids the ability to form
complexes with ions such as Mg2+, Ca2+, Fe2+, and Fe3+. Many humic acids have two or more of these groups arranged so as to enable the formation of
chelate complexes.
The formation of (chelate) complexes is an important aspect of the biological role of humic acids in regulating
bioavailability of metal ions.
I'm so high right now it feels like my head's floating mid air, all thanks to high vpd 
2 weeks flower today Ghost train X HAZE NUMBER 
if u don't know what onset is I will post it on my wall when it comes time in few weeks when I PK mine
