Progressing on legs but not chest

[Couchlockd]

I don't know if I'm doing something wrong or not but I just hit a PR squat on a weight I haven't hit in a long time and one problem
When I train legs/back I hit them hard and I hit chest/shoulders same way same intensity except I'm not making any real progress on my bench at all
I've been stuck on the same weight for a while now and I dont understand why my chest isn't getting stronger

Few days ago had a PR squat attempt out of nowhere and it went up good. I know I could have added another 20lbs and get that but I stopped where I needed to
Anyway, what am I doing wrong on chest or shoulders? I hit chest/triceps hard and go heavy so right now idk why my bench isn't increasing at the same rate as my squat/deadlift

I'm running nsus 5/3/1 its similar to wendlers 5/3/1 except there are a few differences where you hit heavy weights each week with no deload or dropping the weight one week out of the training cycle

It's form.

I can 99% guarantee it.

Watch Jen Thompson bench 101, 201, 301, 401 and 501 on YouTube

You'll gain 40lb increase almost instantly in reps

That coculd be the case but idk, right now i think it has to be my training and im hitting legs too hard each week and cns is having aa recovery issue since i;ll either spend half a day sleeping or tired in the next gym session until im healed up


Thinking i need to aadd in some more volume on chest and triceps, it has to be training
I've been doing a lot of heavy rep work for my accessory work, might be time to go back to only heavy singles and triples and heavy accessory work with more less reps/higher weight
