Deja you're just plain a root rot magnet. There HAS to be something.....somewhere....in your system that is repeating. In other words you are growing LOVELY plants and then they crash. EVERY time. And I've been paying attention.....you've tried VERY hard, worked at EVERYTHING you've been asked to do....bought whatever you've been told to buy and done whatever was suggested. I'm honestly not sure I've seen anyone work harder to correct a problem than you have.

That's why I'm so sorry we haven't been able to pin the issue down for you.

Are you using a zyme product/and or your peroxide? Can you get a photo? Have you tried thoroughly bleaching all your equipment between grows including all tubing etc?

How old is your zyme product or other nute solution? Could they have been contimated in some way?

Can you keep a written log.....even a line or two a day may help us figure it out.
