Make sure you can deadlift properly for a meet first: knees locked, hips through, shoulders not slumped forward. I'm not saying you do any of these, but it's worth checking.
How you train it is up to you but anything that mixes deadlifts and quick increases is something to be approached with a lot of caution. Given it is going to be your first meet, focus on going 9/9.
I'd recommend one heavy day (85+%) every 10 days or so with a light to moderate day (60-75%) in between. For heavy days focus on singles. Add to that plenty of heavy dumbbell rows and plenty of GHRs and you're probably going to be fine. Add in reverse hypers if you can.
