General hydroponics feeding schedule

[A2Michigan]

I’ve tried to use the Lucas formula and it doesn’t seem to work for me. I have a ebb and flow system with a 55 gallon drum. I have general hydroponics nutrients and I do not know the ratios to use. Please help! I grow under 600 watt metal halides

II hope you've had success adjusting. I'd be interested in how you dial in your nutes with your ebb & flow. Happy gardening.
