I'm not sure what's going on with your diet, since whole chocolate milk seems to be approximately 3,328 calories/gallon. You could try adding more high calorie starches.
I think your biggest problem though is your training. The majority of your strength training consists of HS holds and variations of dips (none of which are seem to be weighted). It's hard to grow with isometric training. Also, when your prime movers (the large muscles) aren't getting stronger, there's not much incentive for your body to grow.
Basically, it seems like you're focusing more on skill work than strength work.
