Hi,
I used to deadlift with small weights and have recently started to increase the weight for Barbell Deadlift.
I had calculated my one rep max for deadlift around a month back and it came around 205lbs. (I was able to deadlift 185lbs for 4 reps) and then i used the calculator on this website:

After that i went back to lifting smaller weights (around 95-105 lbs). Things were fine till here.
But in the past two weeks I did 5 sets of 4 reps of my 80% to 90%.
First week, I did 90% (185lbs) and the next week I did 80% (165lbs) and on both the weeks, once I was done with the deadlifts, I started soreness in my back area (hopefully it's just soreness). The soreness lasted for an entire week but at different places of my back at different times. Although, the soreness reduces slowly and goes away completely in a week. But then my next deadlift session comes up and after I am done with my session, helloooo soreness.
I have never lifted this heavy before, is it because of that? Or did I injure my back?
It's highly unlikely that I would have injured my back but I still wanted to check on the forum.
How do I differentiate between and injured back and a sore back?
Here's a video of me lifting 135lbs today (couldn't get anyone to record on the heavier days),

I was looking for criticque on my form and mistakes I am doing.
I have watched several videos on common mistakes while doing deadlifts by Scott and others too and 1 mistake I saw was that my hips go up before I the weights come off the ground and I am still working on it.
PS: I don't touch the weights on the ground on purpose as it messes my rhythm if I touch them to the ground. The weights in my office gym keep rotating on the barbell which makes it difficult to touch them without the barbell moving forward or backward.
Please help me identify the mistakes which can help me peform the deadlifts better and prevent injuries.
