After adding nutes for VEG stage, and once VEG stage is over, should I flush the water when I am ready to add FLOWER nutes, or just throw them in on top of the VEG nutes which have been in there?
everyone has their own way with that one. when i go 12/12 i let them run in the veg nutes reservoir for a week because they a stretching a lot then. i top off the nutes though with flowering ferts. then at the end of that first week i use a full flower fert. its all personal preference which is gained from personal experience. try something different the first few times and see what works best for you.
