A transplant?a simple transplant no matter how late it is with solve most problems with deficiency or nute burn or overwatering and under watering. diagnosing deficiencies is hard but any easy fix for most issues is a transplant. unless its insects....
Isn't 5.8 too low for coco? Bump it up to 6.0-6.2.
here are the healthier plants, at a different location If a pro could check this out I would be grateful.

This garden is your healthier one?
Your in big trouble kid. WAY OVERWATERED!
The leaves should be reaching for the sky. You are snuffing out the oxygen they need...ie.... suffocating them.
I would back WAAAAAY off on the watering and let the leaves get the oxygen they need to absorb the nutrients.
There are very little to no spider mites.
That GH Calmag isnt great for coco.
I cant see any purpose for it in a coco grow. No way do you need a 5-1 cal/mag ratio.
Shit you dont need any calcium. I foliar sometimes...
If you need mag use epsom or magpro sparingly sometimes.(avoid during stretch)
Anyway, you probably arent overwatering.
Are you underwatering?
You dont really need much runoff, just make sure you keep the entire pot moist and dont let it dry.
I have been growing for a long time but this coco coir lockout/calmag/potassium deal has always confused the hell out of me. Would love to master it.
