How much weight to gain per week for natty lean bulking?

[Buster Brown]

What aspects of my training should I change?

You grow out of the gym, not in the gym so the first thing to analyze in terms of your training is frequency. Are you training for pure strength and size or a certain look? Without knowing your exact training routine its hard to criticize. If your current routine isnt working for you in terms of gaining then it's time to change up for 8 weeks..... Then change it again. If your game write up your current routine.

I count out 4,100 calories in a little notebook using a calculator and food scale every day. I have gotten there by slowly increasing calories when I stall gaining weight. I eat every 2-4 hours, and get at least a gram of protein per pound of body weight, with at least 50 grams of fat. The rest is spillover from either of those macros but mostly carbs. Every time I add calories it is in carbs.

Training: My split is Back, bis, abs; Legs, calves, shoulders; Chest, tris,; repeat.
4-5 exercises per muscle group, always 3 sets or more (I do not count my sets, I do as many as I want)
I go as close to complete positive failure as I can every set excluding 1 warmup (I do not count reps, I go until I can't move the weight any more)
The last set of every exercise is a drop set or a rest pause (go to failure, rest 15 seconds, go again with the same weight)
The mantra I follow is: Go until I can't go anymore, don't pause for more than a second. Keep the tension on the muscle, so if I do pause pause at the contracted point of the movement. Come as close to complete positive failure as is possible. Give it everything.
