is it a powder or liquid.. i have powder to apply at night for a snack by spray ( only a verry little of the mix). and when i feed i use the foxfarm trio. grow big ,tiger bloom, big bloom, which is liquid i also use a root stabalizer to help the rootzone obsorbe more nutes. depends on pot size and plant size... i use smartpots, which breath so water and food evaporate quickly, therefore i water about once a day. i feed about everyother day.try to make sure your soil doesnt consistantly stay too moist, you dont want to rot your roots
