I have a 630watt CMH light now. I ditched the leds
I edited my post as I realized this after
Was not feeding cal/mag when using led i had no problems.
My led was 600 watts but only pulled 265 watts from wall. My CMH is 630 watts witch i was running it on that but now i dimmed it down to 350watts
that most likely will help

I am not familiar with that set of symptoms and like @Prophetiko said maybe a combination of problems. I am sorry I cannot help on this one.
To be honest, one of the issues looks like a cal issue and seems to be spreading like one. Those rust spots, the way it's spreading, and if that leaf curl is on lower leaves, all say it could definitely be a cal issue. I'd try adding a source of calcium and watch the plant for a week or so. If it's working, the spreading will stop. There's nothing you can do about the damaged leaves, so watch the new growth and that it's not spreading further.
Just mixed up some cal/mag hope this will fix the problem!

that flush you did, in coco if you use only water, you have likely screwed up the CEC,... did you get pH and ppm reading of the run-off? That's key to seeing if there's any nute salt build-up and off pH in there,.. coco likes lower pH than true soil, 5.8-6.0,....Symptoms look like bad P defc., classic dark large patches of necrosis,...wasting,... could be a micronute defc. kicking in too (Mn), hard to be sure just yet..... we need full accounting of your feeds: brand, dosage, pH/ppm, res' change frequency,....water source, pH/ppm,....any hiccups with pH in there?
Flushing in coco must be done differently than true soil... recommendations I found are RO/Di water, with 150ppm Ca-Mg, plus 150 more in nutes, pH to 6.0, and poured through until run-off is at or near input values,....
... with any luck the CEC isn't screwed up, you can try getting a good PK booster in there ASAP,... I'd look into getting a dedicated micronute supp' as well; Earth Juice Microblast is my fav',.....
