hello from Canada everyone I'm a new grower and have been reading many articles posted on this site and found many that have helped me already. but I do have a question or 2 so ill start with this for now. I'm growing 4 Indica plants in soil under a 600MH they look healthy enough but after 3 weeks they are only 6 inches tall with 4 internodes is this a average height for a plant of this age oh and also would this be a good time to topped them?
