feeding help (fox Farm)

So I'm in the vegetation stage stage and I'm getting ready for my first feeding. But I'm really confused on how much of the water to give the plant, do i give it the whole gallon or just until the soil is moist and i see a little run off. Any help would be great thanks

I'd go with the 'little runoff'. Others may tell you otherwise. How big is your pot? What kind of soil do you have?

I have the fox farm ocean blend. and its in a gallon pot

Show a pic of how big the plant is if you can. A whole gal for 1st feeding is way too much & if you're in soil watering until run off might be too much as well until the roots are developed more. I like to water the edge/sides of the pot & not just drench the pot, so the roots have to expand out for the water. Keep it moist but not saturated. I know watering until run off (20%) is mainly a coco coir thing but for me using soil now I'm having much better results watering with less water & doing dry backs. I love seeing pearly white roots in black soil!
