Potassium silicate in hydro

I take an old bottle and pre-mix it for a 1% solution, and then shake it up before I add it to the reservoir.

You can follow this from customhydronutrients, and then shoot for 1/10th to 1/20th the ppm application rate. Eg. 38mL per 10 or 20 gallons, instead of per gallon.
