well when your plant starts to get taller just tigh it down sideways it will keep yoour plant alot smaller and give you a better yield. id start with 18/6 for like a month and then drop it down to 12/12..
pre mixed potting soil sold at your local hydro store and you should try to get A somewhat bigger grow room. like two rubbermmaid boxes stacked ontop of each other?
if your plant is yellow and soft you need more nutes
if you leaves are green your using the right amount.
if your leaves are crunching at the tips you have too much nutes.
