Lowlife Hindu Kush Auto feminized.

Im sry if im posting this in the wrong section, but since i am a newbie at this i thaught this would be the place for it.. Ive got a couple of Lowlife's auto Hindu kush thats about 30-40 days.. and from what ive seen, my plants seems to less bushy then the ones ive seen here. Im growing them under a 400w HPS light, watering em in a small dose basically everyday. Ive been giving em some basic grass fertilizer.. (the small little blue pellets).. Ive recently topped the plants, wich gave some nice results.. Well, i guess what im trying to ask here is, is there something wrong with my plants, since they're not THAT bushy??..

Anyways, great looking forum, looks like i can learn a thing or two here..

"The plant in these pictures are about 40 days in.."

what are you growing in dude ?? just the expanded clay ?? just feeding grass fertiliser !? .... i think thats probably just superphosphate ... well im surprised it looks as healthy as it does really ... well done !

im using some regular soil, didnt give it that much thaught tho, its my first try to grow some, and basically just threw something together.. Im giving em grass/lawn fertilizer every 3rd day, and sprinkle some rainwater on em everyday, and a flowerspray to spray some water on the leaf's and the stem.. Im just trying to keep it as simple as i can right now..
