ha ha non paedo nutes well done, still you are paying some multimillionaire thousands of pounds to buy his watered down nutes .....and non nutes cos theres only so much npk u can flog, and if u need 150l to yield 500 g u are growing in depleted soil and must need a shit ton of liquid nutes...thats why soils are light...u spend more on nutes, ive yielded 620 g off one plant in a 50 l organic....most new growers would get far bettr results if they spent 15 mins making a simple ammended soil to get em to week 4 flower then use organics or spend a good few hours and make the full monty, u wont go back lmty
