i'd say go with anything that is indica dominant, i find that certain sativa dominant strains are "nute pickier," on a two of my early dwc grows (using same nutes container), my hazes would have nute burns on the lower leaves... i had to separate and try to readjust the nute strength before all was okay...
fyi: i use dyna gro (dont know if that had any affect compared to others)
