Azomite chelate

Hi
I would like to hear any suggestions on chelating Azomite for a DWC system. I have made a some using the below recipe, but I haven't used it . Any suggestions before I do?

1 Tbsp PH down (citric acid, phosphoric acid and ammonium
phosphate) http://www.genhydro.com/genhydro_US/msds/pH_Down_Wet.pdf

8 oz Apple Cider Vinegar(5% acetic acid + micro nutes) http://www.nal.usda.gov/fnic/foodcomp/cgi-bin/list_nut_edit.pl

6 Tbsp of Azomite http://www.azomite.com/index.php?option=com_content&view=article&id=66&Itemid=11

I am estimating on using 1 Tbsp per gallon will act as ph down plus micro nutes. To get my PH between 5.6 and 5.8, will be using GH PH down aswell.

I wouldn't use any phosphoric acid, ammonium phosphate or vinegar in trying to break down AZOMITE. The rare earth in AZOMITE act like magnets for phosphorous and form stable complexes and precipitates which is not the goal to make them more available for plant nutrition. Also, high phosphorous can be toxic and is not conducive to healthy growth of mycorrhizae and beneficial bacteria which are the organisms that exude their own natural acids to weather the minerals. Lastly, high and excess phosphorous and glyposate(organo phosphates) are now becoming a pandemic in our waterways, our growing fields,our feed animals and our own bloodstreams due to the constant use and overuse of heavy NPK and ammonium phosphates in fertilizers and many of our foods. High phosphorous in the blood leads to acute kidney injury, diabetes, bone loss and [FONT=&quot]Hyperphosphatemia. There are a host of other more natural nitrogen sources to add into the mineral mixture that would work even better.[/FONT]
