We're gonna need a lot more info than that. What's your medium, watering and nute habits, how old is your plant, is it in veg or flower, what's your lighting setup, ventilation, etc., etc.

A pic would also be a huge help.

soil, 200 ml every 3rd day, Hesi nutes once a week, 29 days old(vegitating), the plant is on my window sill. it gets 15-16 hrs direct sun everyday, plenty of ventilation (strong wind has actually made a beautifully thick stem), srry camera broke couple days . thanks again
