Same ? As everyone else I feel. Problem w starter???

Ok. Im on day 5 of feeding my starter and it is doing NOTHING. No bubbles. Obviously mo rise than. Room temp stays at 71-74. 

Im trying ( for the first time and Im a very novice baker) to do Robertson’s Country bread. I have done everything according to his recipe on his website. It is a little more detailed than his book Tartine. After day 3 of making the initial mixture, it started smelling pretty funky and it had rising ( maybe doubled) during that day so I started the feed the next morning (Friday). Every morning I dispose 80% and feed the remaining 20%. It comes to 25gm of starter that I am feeding w 50gm H2O + 50gm bread/whole wheat mixture. 

Should I start over from scratch?? Not sure where/what I did wrong here.. Any ideas would be much appreciated!
