No stress I say...life is easier that way.
Reread your post that I quoted and I think my points should be spot on. You did say, "DE contains between 80 and nearly 100% silica depending..." (maybe you meant SiO2??).
But here's how I look at it--if I add 1ml/gallon of Potassium Silicate (7.8% silica) to my "mineral feeding", then in 1 gallon the amount of Si should be 20.6 ppm (1 ml ÷ 3785 x .078 x 1 million)...not very much to be converted to poly then mono silicic acid.
Using the same facts...then the equivalent SiO2 would be about 44 ppm (20.6 ppm ÷ 0.4675).
Now, if I water my plants 32 oz of mineral solution...(1/4 of a gallon) then each plant might receive about 5 ppm of Si (20.6 ÷ 4)---hmmm, very seems like a very tiny amount.
How much Si do plants need? More than that I believe.
