is there enough silicon in most hydroponic 2 part nutrients?

I'm using canna aqua atm in my recirculatiing sytem. Apparently there is a lot of silica naturally occuring in soil but none obviously in any innert growing medium; I have also been told it isn't possible to put the required amounts of silicon into 2 part fertilizers. Does anyone know this to be true and does anyone use any kind of liquid silicon with improved results?
Thanks

I use dutchmaster they dont add it to nutrients so I use their silica @ 2ml per gal

I'm new at this. Being my first grow and all. But I'm using advanced (snake oil) which I know most people hate. However, I skip their silica additive ( I think it's rhino skin?) and use Dyna Gro Pro-Tekt. With this being my first grow, I don't have any experience not using it. But it's supposed to support healthier stem growth and what not. And I can say it's definately done that.

This lady is a little over a foot above the soil. She's one of my strongest clones, and she's had Pro-Tekt every time she has nutes. The stalk is already huge for her size.

You have it largely spot-on. Soil is silica-rich, and hydro nutes contain none. There's no way to stabilize silicate in a concentrated solution except as a freestanding, somewhat alkaline silicate prep like Rhino Skin or Pro-Tekt.
Silica is not considered an essential nutrient for weed, but it does seem to make the plant physically and physiologically tougher. I use it in my salt fert preparations. cn

Thanks a lot everyone. My main reason for wanting to start using a silica additive was to help gaurd against botrytis.

I never had any problems in soil and my environmental conditions have not changed. Do you guys have any problems with botrytis when using pro-tekt?
