Also, you could go one of two ways. You could keep your weights the same, but cut back the volume. Or cut the weights and keep the same volume (minus drop sets and rest pause sets)
I use the reduced volume approach myself. It's really all mental, but keeping weight high and reducing volume just feels less like a deload to me, but it gives your body a break all the same.
You also don't have to deload everything at the same time.
My routine is based on PHAT. Upper, lower, (power) push, pull, legs (hypertrophy).
If I stall on a lift on my power day, I perform one less set on all related lifts for the whole week. I also remove any drop sets or forced reps if part of my routine.
Example, I stall on BB flat bench (my primary power chest lift). Any chest/tricep/anterior deltoid exercise gets reduced by one set.
Usually if I stall it's because my diet or sleep was subpar. So I also focus on that and make sure I get back on track.
