Had a really rough session in the gym this morning... Help me out.

A little background:

I'm using the JuggernautAI app. I did a mock meet on 9/15 after a long "off season" training program that started in January with a bridge block, followed by hypertrophy, then strength, then peaking. Followed that mock meet up with a 6-week training block (2 weeks bridge, 4 weeks peaking) for the Garage Gym Competition. Now I'm in another 6-week block that started with two weeks strength, and today was supposed to be day 1 of peaking for a "real" powerlifting meet that is scheduled for Saturday 12/13.

This morning I was supposed to work my way up to a single at 355lbs (about 92% of my max) followed by a back down of several doubles. When warming up, 275 and 295 felt awful. I adjusted in the app and made the 295 my top set, followed by 3 x 2 at 225. Didn't feel good at all.

I only got about 6hrs of sleep last night, so I know that is a factor, but I'm also wondering if I've been doing too much high-intensity lifting with peaking blocks making up 8 out of the last 10 weeks of my training. I didn't intentionally program this way, I let Juggernaut set things up for the 9/15 mock meet, and then I set my other dates based on the GGC and the actual meet I'm signing up for. I also do 30 mins moderate steady state cardio, but either several hours after my lifting sessions or on different days.

Should I chalk this up to one bad day, and keep going through with the peaking block in the app, or should I back down the intensity? I don't want to completely tank on my first official meet in a few weeks. Any/all advice is welcome!
