not exactly mate. it might be the same chemicals in it but you cant put hydro nutes into soil/coco as they work at a different ph. the water your using is about 7.2. hydro nutes work between 5.5-6.3ish. anything outwith that and the nutes start to get locked out. fucking up phs and causing nute defs is something i am familiar with lol. if i dont keep mine in those peramiters they get sick within hours. soil/coco nutes iether work at a higher ph or bring it down themself, im not sure but iether way i couldnt use them in my nft as my babies would most likely die.
