Let coco dry out, now they won't drink?

I have two pretty big bushes, about 5 feet tall, 4 feet wide, in 5 gallon pots with botanicare coco gro coco, and am using H&G Cocos A+B, CalMag+, drip clean, and Botanicare Hydroguard as a beneficial bacteria additive. I have 10 smaller plants also in 5 gallon pots that go 24 hours between waterings and never get dry...me being a coco old-noob (coming from RDWC, havent done coco in 6 years) I forgot the bigger plants would drink a lot more, and over the 24 hours the pots got bone dry...twice! I know..stupid...I let it happen one day, then again a few days later...I watered right away but they were already drooped.

I read that letting coco dry messes with the salts, so I flushed with 5 gallons of RO water with just hydroguard in it, pH'ed to 5.7. My runoff from the last gallon of 40ppm flush water through each was still 350ppm....I was feeding at 600ppm....so I take it this means there is still a shit ton of dried/built up salts and I need to keep flushing? Also, the first gallon of runoff came out stinking like an aquarium and the pH was 7.5-8.0.....I think this means some roots have died and I might have a root issue now? They were probably only bone dry for a few hours....and I mean just the top of the coco was, I'm sure there was some moisture in the pots..just extremely light.

Am I fubared? I flushed again today with 2.5 gallons each plant, input was 40ppm (from the drip clean) and 5.6pH, runoff was 250ppm 6.8pH. They are not drinking much at all, there was almost as much moisture left in the coco as there was yesterday after flushing...I think this means a lot of roots are dead :(.... Do I just keep flushing until the runoff matches the input ppm and pH, or should I give them a few days to see what the roots do?

Another option is to transplant into 10g pots I guess....so I can check out the roots better...is that a viable option at 15 days into flower?
