First everything is depends of what kind of soil you are using for. If soil is enough with natural nutrients then I suggest not waste nutrients and water flowers with ph balanced clear water. Water feed with O2, like water in fish tank, because O2 is very important for root system and roots will absorb more from soil nutrients.
Start using nutrients when flower will show its needs or when your flowers turn to bloom.
Have a nice harvest!
