What has happened to my plants?

More water. Seriously. Put the pots in trays and put the water to them and then let them wick it up.

The other way would be to just water them more often.

They look better and sometimes after a mistake is corrected they will continue to yellow and look bad on older growth for a few days. The damage is done and won't reverse.

Watch new growth to know how the plant is doing.

They look better to me. I had a similar issue and found that the damaged leaves are doomed to die off anyway, you can't bring them back.

Curious to see what your yield was.

You have an Mg issue for starters (nothing new for a coco grow). Second, don't let your medium dry out...you're using coco...it's not soil...if you allow it to dry out your plants are going to burn. Thirdly, again, you're in coco, don't water with just plain water. Anything you give your plant should have some nutrient in it...but not just plain water. Fourth, remember you're in coco...the only food your plants are getting is coming from your water / feed. If you don't add nutrients to your water (and you need more than just calmag) your plant will go hungry. Again, being you're in coco, you need to manage you pH as such...again, it's not a soil grow, so don't treat it as such. Coco is a great medium, but you have to understand it's idiosyncrasies to be successful.
