growing 6 inch plant just bud NEED SUGGEST

im tryin to grow a 6 inch plant but all bud..when can i use nutes..light cycles

once its well rooted you can use nutes, depending on the soil and the amount of nutes in it. switch it to 12/12 asap ....you know that you wont get really any bud....maybe a blunt

yea i cant have a big plant here.. its just to see if it would work.
