You are confirming me that I need a calories surplus, and I'll need 1,000+ since I'm an ectomorph, but what I am really wondering is WHY does your body need a surplus. Also I am wondering if I could eat junk food like a 1k calories pizza at the end of the day if I'm missing some. Last question:P Do I need to eat as much calories/proteins on the days I'm not working out?
If you are indeed an ectomorph, you definitely do need a larger surplus. The reason behind this is as follows:
1. Your body will use the the surplus to signal anabolism, and thus growth. On a maintenance diet (eating at required calories) or a deficit (below what you need) your body will NOT achieve anabolism, and will instead prioritize the use of the calories based upon what your body needs.
2. When you are in a surplus, you guarantee that your body has everything it needs, and more, in the event that you are not able to properly calculate an exact figure (which is nearly impossible). This overage covers the gap between your calculation and actual body requirements.
3. Surpluses by the end of the night tend to keep your body into anabolism for longer while you sleep, which is essential for mass building. When you sleep, your body goes catabolic unless a good surplus is present - or in the case of professional bodybuilders, you wake up every 3 hours for a shake.
I can go into the scientific reasoning, but I feel this is unnecessary with the explanation above.
With regard to the pizza - it all depends what macros you need. It's always better to eat 1,000 clean calories than 1,000 dirty, however if you have 300g protein already ingested for the day, and you want to throw down some pizza for the grand finale, you can most certainly do that. I would just advise to consume olive oil with the pizza to balance out the fats.
