I will grab one from a slurry test here shortly....:smoking: great to hear Pete! I must admit, I'm baffled at why you used a 0-10-0 nute soln. to flush in coco, since it's the Ca, Mg and K balancing act that needs dialing in, but likely, it was the flushing in general that helped most,... those ppm were high, and you might have had some lockout/tox' issues starting,... as long as the newer growth looks good, and symptoms are halting,.. the more hammered leaves may still croak out, but that's normal enough, the plant cutting it's losses there,.... got some pH reading for me? This will help figure things out,....
Here's why I used that specific product....it's going to be hard to read so let me know if you would like it typed out. Only reason pot my trust in this product is the backing from my work and bosses. They love the stuff and I've sampled and checked bag appeal from this product vs others from the same run on same strains and environment from same clones and it tasted better, looked lighter green and was the smoothest!
Check out the line @pop22 and @Waira
... But good, direct feedback like that is golden, so I'll keep it in mind Pete! The slurry test sounds a bit touchy, as the meters were made to test liquids, so getting it fully sluchy is critical for accuracy,... and immersing the probes into that much will foul them quickly, so look into cleaning solutions for the probes, and make sure to rinse with RO/DI between every test, and store it in proper solution for this,... 
pop22 gonna brow beat ya on organics! And the results are hard to argue with,... 
... but it's a whole 'nother learning curve, because the soil life is EVERYTHING in organics, and making them happy is a different ball game, different tools on the belt,... but you'll have many fine organic growers to brain pick! Pop22 just volunteered!
