They all grow different brother. Right now it looks like you've got a tent full of healthy plants. There is a difference between growth and stretch too. Dont go re doing your whole set up or tearing those down because other people have massive plants. Ive been growing for about a year and am still having those "ahaa" moments. It takes alot of patience and a keen eye. Your next grow will be better then your last. You may kill a plant or two in your lifetime; but you'll learn from that experience. Those grow lights are top dollar. My first grow im certain i chopped way to early. Before i keep ranting. Like i was getting at. Love,patience and a watchful eye. ..the key to every womans heart. And beautiful buds.
