At your age/experience you would probobly get much better gains if you ditched the hangboard for actual climbing. Bad habits are hard to squash - get good technique and movement habits first then get strong. The long term gains will be greater (and you will have a smaller chance of performance crushing injury).
Edit to add some more info:
I would say that the risk of injury is very great at your age/experience. Tendons/sheaths/pullies take longer to react to stimulus and strengthen then muscles do. If you screw up a pulley/tendon/etc. it can be a serious long term hassle.
For nutrition you should be eating 3 servings of different vegetables and 3 severings of different fruit a day minimum. Nuts have a lot of important nutrients in them but they also have a lot of fat, so moderation is the key there.
You should be getting most of your energy from carbohydrate. Don't believe the meatheads that claim that you need obtuse amounts of protein.
If you want to learn more about nutrition (and I would encourage you to) "Gold Medal Nutrition" by Glenn Cardwell costs around 15 bucks on amazon. It is a great read.
