in soil a plant could easily grow for 3 weeks or longer without ever needing nutrients just depends on how much nutrients is in the soil and how long it takes the plant to use them.
in hydro you use nutrients basicly from the start just starting with a very low strength, waiting a month to add nutrients in a hydro setup would result in a bunch of dead plants.
bejay Reviewed by bejay on . First food I have a grow journal going in "Hydroponics" "5 strains first grow" anyways I thought I was doing everything correctly but now Im aware I might be feeding to early. I watchd a video and they said when you get 3-5 sets of leaves they are ready for some food. Its a half strength and the seem ok on a 2 time per day. I was wondering if someone could elaborate on this some. Thx I-420 Rating: 5
