It was very easy to overdo it and wind up with a level of fatigue that felt more like a back strain or spasm and left me taking a week off from everything. So I relate to your concern.
If I were you I would be very careful with volume on the deadlift and avoid anything unnecessary that works the lower back (e.g. in your BJJ training, avoid warmups/calisthenics that hit the back). Like, say you try for 5 reps at a weight but only get 3. You might think, "I'll take a rest and then try to get 2 more. Or I'll back the weight off a little and try for another 5, to make up for it." That might be ok for most but too much volume for you. Again, my experience has been it doesn't take much to tip over and hit a level of fatigue that is hard to bounce back from.
Also, if you aren't hook gripping (or using straps), I'd recommend it. I used to use a mixed grip but I think the slight rotation that puts on my back (that's how I think of it, anyway) makes little back tweaks more likely. Given that you are a mason and a BJJ guy you probably don't have grip problems (and your hands are probably plenty tough to hook grip without pain), but I offer this suggestion in case it helps.
