Be careful, bleach also oxidizes. Dont want to damage pumps or expensive water chillers. It doesn't take very long for bleach to kill things

I wouldn't worry about this. Think pool chiller.

My setup is pretty much the same except I use well water and have always had issues with blotching. I started using vitanimo for no other reason than it had amino acids that I was curious about. The last three runs that I have used it on were green and healthy through out the grow. Being that my well water is full of calcium and magnesium I though perhaps I was getting a lockout, the product seems to have solved it. Perhaps yes you just need more Calmag being you use RO water, just a thought .

Depends on concentration and duration

I run pretty high concentrations and no issues when sterilizing

Then you're good to go

Looks like to much nitrogen, and a k deficiency. I had a strain whos leaves tacoed like that whenever it was lacking k. And week 5/6 is when most companies recommend a pk13/14 product. Just my two cents. Hope you figure it out.

A 10% bleach solution for a minimum of 10 minutes will kill the AIDS virus, you should be able to have some really safe fun with your system when it isn't full of plants
