I'd first say you root bound. Most people start in a 4-6" pot and re-pot before a month has passed, into a 2-3 Gallon pot. I posted pics of all three of my first plants at 30 days to compare. (BTW they were JUST re-potted before the pics)

As for your dots, could be nutes, PH, or if indoors it might be Ozone damage.
