Little or no Smell

[dou]

hello I'm a bit concerned about my 4th grow, there is very little smell odour coming from my 4th grow despite the fact i'm in the 3rd week of flowering, In a tent outside in the garage, good temps, HPS lights, everything is good from their colour to their overall condition except the lack of an odour, my 3 previous grows all had some issue but always had a nice strong smell, the babies were given to me by my brother who has a similar grow about a week ahead of mine and his are 'stinking' any advice please.
Thanks in advance.

If everything else looks fine I wouldn't worry about it... the smell will come eventually.
