Suggestions anyone.... Plants look like death!

1EC is 500 PPM on the .5 scale I believe

Wrong. I'm amazed you guys don't know this. you wouldn't know if his ppm's are 700 or 500 unless he tells you what ppm meter he's running. There are two scales that convert to PPM. .5 and .7. Blue Lab combo meter runs .5, Hanna meter runs .7. This is EXTREMELY important to note. Next I've NEVER heard of anyone running straight tap water in UC. You MUST have a reverse osmosis filter and add cal mag. Also you should be running synthetic nutes, and you should be taking all the water out and flushing every two weeks to be safe. I would start your plants at 500ppm or less. You're operating a cigarette boat as opposed to a row boat(dirt).

I'm amazed you made this post.

blue lab guardians switch between ec, ppm (.5) and TDS (.7).

its not sorcery.
