My only advice is that you do not change your plan. I don't know what your plan is, but if you panic and make a bunch of last-minute modifications, you will not learn anything from this training cycle.
If your pulls go badly at the meet, you get information that makes you better going forward. If you tweak a bunch of shit now, you essentially waste the whole training cycle.
Also, the deadlift is fickle. If you're relatively fresh going into the meet, you should be fine. My pulls fluctuate week-to-week, and are more affected by my overall physical state than the other lifts. I wouldn't worry about it.
