I have the same problem, just started to overcome it.
My chest is my weakest part of my body, I can also throw up 225 for 5 though, but growth is the slowest in my chest.
I feel like I hit my shoulders too much when I do chest, my shoulders are waaaaaaay larger in comparison too. My delts are big. Wish I had the same thing going for my chest lol.
Lately I've tried doing different things like holding the contraction longer, various rep ranges, slow negatives, and less range of motion on bb press since I'm tall (stresses the shoulder less this way and lets you focus more on your chest by keeping your chest contracted throughout the motion). Seems to be working now, but I'm in a cut/recomp. Definately noticing more definition and more of a ripped look on the inner/upper pecs now though, which were lacking before.
