Liquid fertilizers (and other enzymes, sprays, premade soil products, etc) will produce bigger plants in shorter time, but I'm super wary of that shortcut because I know it comes with down sides, and down sides aren't something I'm okay with when it comes to my medicine, since I'm literally keeping myself and my wife alive and functioning with cannabinoids.
But they look big and busy and green already, can't argue with that :D
