Looks like either a sulfur or a magnesium deficiency, the plant is pretty green so I wouldn't be giving it any calcium and magnesium supplements they all have nitrogen. But that wouldn't stop you from using some mag sulfate or Epsom salts, you want the unscented pure salts. You can do a foliar feeding of those and you don't have to worry about throwing off your soil balance.

Thanks Jingo. That's what I was thinking. I'm growing in foxfarm ocean forest. So really haven't been giving her much nutrients except here and there. I did give it a little cal-mag a week ago. Just been flushing with RO water the last 2 waterings.
She's had a pretty long veg too...
I did hit it also with some boomerang before I started flushing.

Yeah when I was in Fox farm I didn't feed until late in flower, mostly I would just repot it when it started to get deficient.
