Add it now why waste some easy made money At 50 uniques / day i don't think you can make more then 1$ the best 2$ Adsense is about traffic Traffic = $$$$
I say sign up right away. You may not get much in the line of money quickly but you will start to see patterns and it will help you develop the site and the way the ads are placed. Why not make even a couple of bucks over 2 weeks while getting it all together rather than nothing until your hit count is up. The people come to the site for a reason, get ads that support their interests up.
Another reason to sign up now is so Google has time to get the right ads. When I started my learn Spanish site and again when I redesigned and all the URLs changed, I was getting a lot of ads for learning English or completely off topic. After 1-2 weeks on average, longer for pages with little text, things settled and the ads are great.
Yes You should Place ads, My case is same as yours. i get arround 100-150 unique visits a day and i placed the ads from the very first day and its arround 2 months i have earned $25. So i would suggest you to place ads as it will not affect anything rather you will get some $$. In the start it may be less but it will keep on increasing as your traffic increases.
