raffy has given you some good advice there bro.....read it.....
when i first started lifting i was 6ft 4 and about 14stone and not in great condition, 4 years later im 6ft 4 16 stone and have some decent pbs in my lifts....and i wouldn't say i had the genetics to be a bodybuilder, i have had to work for every last pound of muscle, like you might have to, remember at your age you will have an extra ability to stay lean and build muscle, you are anabolic most of the time, the best advice i can give, is to go back to basics and train on a split routine 3-4 days a week, i find this works best as an all-round routine for most ( or at least me anyway ) ............
try either:
day1>chest/back day3>lower body day5>shoulders/arms 4>days off OR
day1>upper day2>lower day4>upper day5>lower 3>days off
either of these methods will work for a while so give em a try, if you opt for 3 days a week make sure you go all out every session, volume isn't key there.
and with upper/lower have a heavy and light session within the week.
Eat plenty of food, concern yourself with consuming the calories dont obcess about clean eating your main concern is trying to mass up......keep going, stay consistent and keep a log, you'll be sure to succeed, but it takes time....it isn't rocket science but it is science, so pay attention and do some research.....
good luck bro.
