You need a break...There, I said it
I'd drop the intensity for around three weeks and work some assistance lifts hard. Then jump back on your 90%+ routine prior to the meet. Work back up to your max, rest a week, then hit a PR at the meet. But that's just the way I'd do it, but I don't compete, so take what I said as a suggestion. I'm sure the competitors will have some good suggestions.
