New to deadlifts

[Darkseidd21]

I have only deadlifted twice in my entire life due to low back problems but recently I was reading about sumo (being easier on lower back) , I started with rack pulls bellow the knee just to get the form kinda and I do it with an empty bar.When should I switch to sumo,and any tips on how to progress with dl, cause I think I'm not ready yet to go heavy on dl?

I don't think it's a good idea to switch to a variation to avoid the complications of learning the lift, in general. For that reason, I'd recommend you upload a form check with, say, 135 on the deadlift just to see where you're at with the form. Until you've got that confidently, progression is irrelevant.
