I dont feed my plants ever watering . I feed my plants once every 3 weeks to a month . I tried feeding weekly when I didnt know any better and I burned my plants up . I use liquid kool bloom and calimagic and I use fox farm ocean forrest soil . I dont feed anything to my plants until the buds start popping out and I found out thats the way to go for me , and the quality is really good and they look really good at harvest time .ar u the guy that runs autos in soil, I think don't feed evry water they don't even need it even I know that therea are autos
