dont think this is a problem but can you let me know what you think please

hi fellow growers, firstly thanks for looking at my thread any contributions are greatfully appreciated.

currently am growing big bang fem strain they been under sodium lights now for around 2 weeks they have accelerated like no ones business and are looking very healthy and strong all leaves are nice and green and these are in a 6ft nft system.

my queston is they seem to be growing very stocky and short with good size leaves is this the norm? i mean by saying this they are probably around 5 inch tall and 8 inch wide!!!! but none the less looking very healthy

thanks and i look forward to any replies

short and stocky with wide leaves? sounds like an indica, which tent to grow short and stout while sativas grow tall and lanky
