I'm planning to get a hydroponic system and I was wondering if it is ok to use plant nutes as a hydroponics solution. I'm talking about the N-K-P thing.
yeah you can its just some of the nutes are made specifically for soil which will not have some essential elements needed for hydro because the soil provides them. a lot of nutes can be used in hydro and soil though you should be ok unless the bottle tells you otherwise.
