How often should I water with Canna Substra Flores nutrients

Hello, and thanks for your replies....I'm starting my flowering and have just bought Canna Substra Vega & Flores, Rhiz, Cannazyme & boost along with Vermi T (compost tea) & would like any suggestions on frequency of feeding them nutrients in my watering schedule. I'm using a 55 gallon drip system with Sunshine #4 soil mix. Anyone using these nutes in this manner or something close and could share a few words of advice?

im use soilless mix perilite verm peat moss same nutes as you and im feeding every 2nd watering once every 4 days or so
