(switching from veg to flower) Normally you can use the Feeding Calculator on our website to tell you how much of each nutrient to add during the Vegetative stage and then in the Flowering stage. Usually, you mix a fresh batch of nutrient each week. This is because you won't know what amount of each mineral or nutrient the plant has used up.

Many growers will feed one to four times a week and then flush in between feeds or have one day that only gets a flush.
