limited growth on sd

Hi all, I have recently begone wotking with yeast and I'm curious to know 
whether it is normal for them to grow to a limited size on sd media. I 
plate cells on sd media suplemmented with all aa's except the ones of 
interest and upon transformation i do obtain colonies. The problem is 
that after 5-6 days, the colonies reach 1-1.5mm in diameter and stop 
growing. This also occurs when I plate cells on sd supplemented with all 
aa's. Is this normal? Is there a problem with my media? I am making it 
according to Sherman's recipe...Might this be strain dependant (I am 
currently using one strain only)? Any insights would be appreciated.
