Is there a forum going? and where?
If you have a 3-part fertilizer, there are ways to find the right ratio for strawberry's by calling or talking to the staff at the hydroponic store. Understanding basics to water temp, air temp, light, humidity, co2/ventilation, res. fertilizer srength ppm & ph, ect. is important. Nutrient change out is something to look into. I think growing strawberry's hydroponically can be quite rewarding.
Hope this helped.
