Garage door catching on frame

[apacheDIYman]

I have a Henderson Premier garage door which is catching on the bottom right frame when it closes as shown in the photo.

I noticed the cable on that side is much tighter than on the other side. It only has one nut on the overhead spring that can be tightened on the left and I am aware it is dangerous to do any work to it without properly securing it.

However is there a way to change the tension on the cable just one one side rather than changing the tension on the spring itself?

Thanks Ken, I did check out a lot of YouTube videos but they all talk about changing the tension of the spring and not balancing a wonky door or changing the cable tension one on side.
