Well if your 16 then your not even suppose to be here. So they have been stressed out from moving but you still have some buddage going on. Get them in as much light as you can. The stretch is normal and should fill in with bud. The bottoms are tight, you did good for first time. Just keep doing what your doing. In a few years you could be one of the masters here helping out others.

Keep it safe and remember, If you show anyone they will steal it or bust you.
