Transplanted to bigger pot, feeding help, please!!!

[Scoopaloop]

I transplanted to a 7 gallon pot. She is doing great. My question is... Niw that I have to give more water, when I feed it's going to take say 3 gallons for run off, my nutes are NPK raw grow, 1tsp per gallon do I use 3tsp since Im giving her 3 gallons of H2O? Seems obvious that I should, just want to make sure. Thsnk you
