I'm completely unfamiliar with your nutes but they're showing a bit of nute burn ... good on you for just watering her for the last week but you WON'T see any improvement in the leaf tips if you've solved the problem. I'd back off on anything you're giving her that contains a lot of nitrogen... perhaps cut it in half and see how the NEW leaf tips react... You want to start the nutes up again (gently!) because you don't want to have to deal with a deficiency now....
Good luck!
