Fe DTPA solution: adding HCL 10%

Did you notice that it is called "DPTA" and not DTPA on his retail site, but it is labeled as "Diethylenetriaminepentaacetic acid" too? Probably a simple typo. http://greenleafaquariums.com/aquarium-fertilizers-supplements/iron-chelate.html

Yes, I did but, I called before I placed the order and I was told it is DTPA.

I googled to look for a method to identify between them, all I found is some phtochromacy analysis...
