New Grower Feeding help

[sike]

Hey guys Im a little confused. So im 4 weeks into my auto ak47 grow. And its time to water. They are starting to need water roughly 2x a week a litttle less. But i normaly feed them general hydro flora series nutes. But im not sure if i should give them nutes everytime i water them. ive been giving them half strength recommended veg dosage. I dont wanna make the careless mistake of over feedding my girls
