At those weights, your squat and deadlift ought to be going up nicely, even if you started high on bench and rows. What do you weigh? If you're less than, say 80kg, have you been eating enough to put on weight?
I'd recommend dropping back about 4 weeks and ramping up again, but I think it's more important to figure out why your squat and dead aren't going up first. Can you give us more general info? How old are you, what's your diet like, do you drink a lot, do you get enough sleep, are you using freeweights or machines?
