Can low alkalinity burn tips?  Mostly it is high alkalinity.  Before I started dosing my alkalinity was often low, even lower than 6 and it never burnt any tips in my sps.
 
Burnt tips and STN are probably 2 different problems and that they happen at the same time probably means that there is something quite out of wack with your system, not sure what.

I'm going to put all 6 banks on 6500K and just grow the coral out. Once they are large enough, i'll focus on coloring them up.
