did u plant them in a pot or in the ground? try to give as much sun as u can, and u don't anything to bother your plant, like slugs, rabbits, deers, u can make like a small green house. it is what i'm doing for mine. get a piece of fence, make a sort of dome, or whatever u want, and put some plastic foil over, transparent if possible. make some wholes on top so that the rain water can go through. it is actually a preatty good technique, last year i grew a masterkush*KC using that system, and in two months it was trhree feet tall, and i was away for about a month and half.
where are u by the way? good luck
