@AxlWeed,
You should think this:
sun's "full power" hours in an avarage spring, summer or autumn day of the year;
leaves are like rubber tyres, you can use them in an efficient way up to X miles/km;
the structure of the whole plant is very short, compact because of the generous amount of light you give her;
every problem in a plant will become worst if anything of the environment is off (temp, rh, nutes, etc.)
EDIT:
also low rh and "wind" burn (fun too powerful/close to leaves) will end up in a short compact plant with some burns
