why you no smell

I have some skunk 1 its in week 6 first day sat but there is no smell put your nose to it and its a bit peppery but not has strong has i would have thought i have 3 plants under a250 watt highsodium light plants are in hdrophonic system. Are seeds wank or could i be doing something wrong.week 6 of budding.THESE PLANTS HAVE BIG NUGS EVERY THING IS FINE APART FROM SMELL

have you started flowering? it will smell alot after you;ve started the 12/12 light cycle

if the plant looks healthy and growing okay, i wouldn't worry too much
