strange odor in 5th week of flower???Any ideas??

I am currently in my first grow of WW,5th week of flower.about the end of the 3rd week I started noticing a....off...smell.It smells almost mildew like...like wet swim trunks that sat to long.My RH is between 40-50%,temps are 82 lights on and 75 lights out.Plenty of circulation and fresh intake,good exhaust....confused...Is this smell just the dankness of the strain maybe???I see no discoloration in the buds at all,infact they look great.I do however have some yellow spotting on some fan leaves which appears to be spreading,whether it's related is a mystery to me.Any ideas what this odour may be or if it may be normal(crossing fingers).

oh god yes,if not this batch may end up in the trash!!

Yeah I know the smell, and since I am relatively new to growing I thought I had a mold problem. All my plants have had this smell. The smell is completely gone in my cases after the 1st week of curing.
