That might be so but it might not contain the nutrients needed for a budding cannabis plant. Will probably be a more general nutrient buffer say something similar to miracle grow. Nutes arent completely necesarry, i did my whole first grow without them during flower and they turned out ok. I think if you want to get the most out of her you should buy some nutes and a ph pen, this will also speed up the learning process. Im on my third grow and only just started using a ph pen and nutes ! C
