whats this mean !!??

heres pic..growing good all nice green,the few burn spots are from dripping solution on plant not from watering.
thanks for any input +rep

i should mention the problem being the leaves and new growth keeps growing upwards??not laying out

my buddys plants are doing that as well, it doesnt seem to be causing any other problems, i think it may be due to the light being a little too far away.

have an other 1 at same age was doing it last week but now laying out .hmmmmm
