That's great work - heavy DLs are progressing quickly
I should know this, but what program are you following?
I decided to write my own program and really aim it towards my weak points. Every 4th week I'll drop the volume and test the main lifts and the tests reveal what I'm strong at and what weak points I have. If weak points appear then I'll add in an exercise and balance out the volume that I already have or if it's the same weak point I'll increase the volume of the relevant exercises.
The program structure is very simple, Week 1 Majority of the work is ~75% 6-10reps per set reps, week 2 ~80% 5-8per set, Week 3 ~85% 3-5per set and Week 4 deload in volume and hit some 90% work.
Each main lift will then have accessories picked for each muscle used in the lift and as for exercise selection it's my best bang-for-buck that will eliminate my weaknesses and still have a pretty good degree of specificity towards the main lifts. I'll use a lot of compounds variations for this. For example, coming back from my knee injury, my back got very strong because it's all I could do after benching, OHP and tricep work, so when I started deadlifting again I didn't need as much back work but did need a lot of hamstring and glute work. Now this didn't mean I would eliminate back work but by looking through exercise choices my best bets were Stiff leg deadlifts (great for hamstrings, glutes and back and for helping speed off the floor), deficit deadlifts to strengthen the entire chain, and block pulls to also help with improving positioning, hamstrings, back, glutes and core(positioning and lockout).
This meant I had the upper portion of the lift covered, the lower portion of the lift covered, and an additional exercise to bring up the weaknesses. Because of all of these new exercised that would tax the back quite significantly I could reduce the amount of the back accessories that I had previously. The amount of volume/frequency programmed is what I know I can recover from and what works for me may not work for someone else.
My exercise selection is also to do with the fact I'm so far out from competition right now that I don't have to worry about my main lift variations for a good while and can just focus on building the tissue for now, and also, variations are fun.
