It's that last overall shot that really tells the story, and those ladies look terribly overfertilized to me (and maybe heat stressed).
Necrosis from leaf tips back, along with reddened petioles tells me there's a problem with phosphorous uptake. Deficiency or toxicity I don't know, but right now I'm leaning toward a toxicity based on that last photo.
Magnesium problem, based on the upturned leaves and interveinal chlorosis. If Mg is off, that could throw Ca utilization off.
Just saying that everything is "spot on" isn't very helpful to those you're asking to help. Actual logged parameters are what can help others help you. Have you used the Cutting Edge line before this, or is it your first time with them? I've never used them and so can't help answer questions specific to that line, but you said you've run a couple of these lines for a little while now and haven't ever seen anything like this.
Last, but hardly least, and this is based on the one leaf that's still green but quite crispy and obviously not coming back--any flying bugs? Anything in the roots crawling around? I have bugs in my eyes.
