Can she recover?

I've been having a problem with some of my leaves (about 20% of fan and branch leaves) curling under at the margins of the blade. After consulting the forums and FAQ I've come to believe that I have a high pH. I tested my tap water (I know) and it was above 8. So I bought some RO distilled water pH'd at about 6.5

So my Q is this: Can she bounce back? Here is a pic.

As long as you stay on top of the PH, she'll be fine.

So if I just water w/ distilled water will that correct the pH of my soil eventually? I have soil with organic nutrients already in them so I don't mix nutes into my water. I just need to correct this asap cause my lady just entered her 12/12 cycle and I want to stress her as little as possible.

dude, it doesnt look bad at all. i would say confidently it will bounce back relatively easily

That looks like heat stress leave are curling down from stress no burns so its not nute burn move those lights up dude

Stessors

heat - curls down tips turn on the edges
ph - slow growth droopy leaves browing leaves sometimes if roots are dying
light - burn spots curling leaves some times down or up
nute - like hell just threw a gallon of fire in your plant BURNS AND CURLING LEAVES ALSO UP OR DOWN BUT IT WILL BE VERY BURNT LEAVES
