So what typically happens is a heavy squat will fatigue the low back leaving the lifter unable to break his deadlifts off of the floor. So you want to really approach this like you would approach intermediate programming. We have heavy/light/medium days per lift but I find that it helps to treat the squat and the deadlift as one "collective lift." This isn't 100% true but useful for illustrating the point. Squat and deadlift stress overlap and both must be considered when programming either lift. So if you are squatting lighter to deadlift heavier you aren't detraining the squat, you are managing stress. When it comes time to peak the lifts they will both cooperate just fine.
So my advice to you is take weight off of the squat and push the deadlift up. You may have to alternate rack pulls with deadlifts, haltings, or deficits (depending on which heavy floor pull you prefer). Haltings are the default recommendation here and they work just fine. The point is that the heavy squat is probably causing too much stress and your floor pull is >500 for reps so I would first lower the squat and if that doesn't work then break up the pull and move to a biweekly progression for your limit pull. Also, what is your height/weight/age/waist circumference?
