I grow hydro. Dwc. And use advanced nutrients. (Only for the ph perfect side of things. Makes it soo easy!) But there are alot of other good nutes out there that people get nice healthy plants with. I grew in soil for a couple of years when i first started growing. I used liquid fertilisers from bunnings lol. With a bit of cal/mag and trace elements. My results were very average until i started growing in dwc! Some of the guys on here get right into organic teas and making super soils etc. And they get some amazing bud! But too much work for me lol. If you intend to grow in soil i would advise to ask some of the very experienced soil growers....... otherwise you could try your hand with coco? Advanced nutrients do a ph perfect coco nutrient. (Can buy on ebay au) could be a much easier start for you ben?
