AdSense needs lot of text content on the webpage before it can be approved. You have 10 hubs which is a good amount.
However, they also look for the age of the website and viewership. Since you have joined just 4 weeks ago, it will take while to gain viewership. In some countries, Google requires your website to be at least 6 months old for the same reason.
If you already have a blogging site, you could use that one to apply for your account. Make sure you have enough content and traffic before you do that. But in case you don't, you can post more hubs over a period of time and then reapply in 2-3 months or so.
