I'm not a pro but you should ask her questions about her so you can get to know her better, small talks usually get her to open up. How's your day, what do you like to do on your free time, what does she like, favourite hobbies, food, what she did on the weekend ?? I'm actually a noob at this but let me know what the outcome is, as I do have problem with Girls too..

Have fun, enjoy your date!!
Oh yeah ask if she likes to blaze since you do.
