Any idea what this leaf problem could be?

specs-
g13 x silver haze from a mother
600w digi ballast
hortilux super hps
fox farm ocean forest
foxfarm grow big nutes
3.5 gallon buckets
temps between 74-79
humidity 45-55%
put into flower on 5-30-10
closet grow with a non window standalone ac vented out of the roof
2 circular fans

looks like nute burn to me or transplant stress? but i only added grow big one time during veg becuase fox farm ocean forest already has a lot of nutes in it,

any help would be great

over nuted is my guess

should i just give them a flush

yeah i would.
they looked stressed out and you want your flowering plants to stress as least as possible.
sorry i'm not more help.
i had that problem with one of my bitches she turned out ok not the best but it was ok glad i started with bad seed.
