Amino Treatment Replacements??

Whats up guys. I have used House and Garden for years and have done my last run with Amino Treatment. I loved the product but it is out of control expensive. I bought the bigger bottle which is 1l for 190 dollars. They have other products that are expensive but you use such a small amount(1.1ml) that it ends up being very cheap per gallon to mix. Amino Treatment in flowering is 3.8 ml per gal which from H&G is rare. The product is basically a Silica,Amino Acid, and Beneficial Bacteria product. I was wondering if people had ideas of cheaper replacements. I use so many beneficial products that I am not worried about that but I love Silica products so I was thinking of a product like SI(Structural Integrity) from Humboldt Nutrients which is 6% Silica(not Calcium Silicate which is all I cared about) which from what I have seen is pretty strong. Also I have heard really good things about Dark Energy but never have used it. I was thinking about purchasing 1L of that and trying out those 2 products together as a replacement for the very expensive Amino Treatment. Does any1 have any experience with similar products or these products and have any comments or suggestions?

I have also heard good things about Floralicious plus so that would be another option instead of Dark Energy. The only down side I have heard of Dark Energy is smell which I really don't care I have very good ventilation so it shouldn't be a problem. They both look like good products so if anyone has any info on either of both of them I would really appreciate it.

House and Garden has Multizyme/Multizen and Bud XL which are both enzyme additives which I am guessing that is pretty much all Prozyme is. Thanks for the reply though and I will check into it.
