Auto lemon haze day 29 now had to tie too high

Don't be worried about the none flowering after 4 weeks. If it's an auto, you should see it soonish. Aybe another week or two. - If not auto, you have to put it into flower yourself, by limiting the hours of light it gets. What you've done with the rope looks fine.. Once it can hold its place on its own, you just move the rope again, and continue until satisfied. ^_^

That's perfect my friend, very good thinking on your end, that's proper low stress training and will be very good for your plants. Keep on the great care! Happy smokes!
