Adding silica to feeding schedule?

Has anyone ever added silica to their feeding schedule to strengthen plants? A friend told me that adding silica will strengthen plants and help reduce heat stress and sun damage. Thoughts?
 
Just remember that if it's water soluble it will leach out of the medium if you get runoff so probably only good if you're using containers with a drip tray
 
Any suggestions on how often to use it? I fertilize weekly and I flush the soil in my pots well before next feeding.
 
What other benefits does it have other than "strengthening" the plant? Everything i read about it seems a little vague.
 
It's just a nutrient that the plant requires, along with a dozen others
Potting mixes usually lack silica, don't expect a miracle 
 
I add diatomaceous earth to my container mix just to be sure it's (silica) in there. I think it makes for a sturdier plant that can withstand high winds and hard rains better. I have no scientific data to back this up.
