Nooooooo!! Just have a look to different growers useing same seeds, your plants are short and bushi right now, starting to Flower they will rise and make you happy,,,,, my thoughts were same, even while flowering i thought, they are much too small, even the flowers itself, but, honesty, i never grew that huge amount of weed with that small plants and sametime this small amount of light ( 385 W / 1.44m²)
justz be patient and wait....if the start having yellow leaves, do not worry, it s normal...
do not worry, sit down on yours sfa and enjoy the movie :))
