Possible Over Watering or Maybe Root Rot?

[CookiesLikeWhoa]

Hey all, hoping to get some advice on a plant that seems to be on the brink of death.

Strain: Ethos GMO Zkittlez
Day 33 of Flower
Medium: Coco/Perlite 50/50 using Auto Pots
Feed: 'The Recipe' minus the fulvic acid. Also using UC Roots to keep the res stable.
PPM: 1150 or 2.2 EC
PH 6.0
Water Temp: 74F
Air Temp: 92F
RH: 50%
PPFD: ~1000 on the tops ~500 else where.

Yesterday the plant was looking fabulous, today when the lights came on it looked like this.

You can see her sisters in the tent around her, on the same Auto-Pot system.

Leaves feel moist, not dry or brittle. Medium is wet for sure, auto-valve has plenty of water in it. Her media is no more wet or dry than her sisters, only thing that's change is how hot it's been. Last night was a burner and the tent only got down to the low 70's after the lights went off at 5AM.

I figured if it was something with the water or environment, her sisters would all the look the same, but they all look as happy and healthy as they have always been.

I'm a novice grower, but it looks over watered to hell and back, but I've never experienced this in coco, or with the auto-pot system. Any advice would be amazing!

Just to update this, we chopped her yesterday since there didn't appear to be any improvement and she only got worse.

Pulled the plant out of the pot and while the roots appeared okay and there wasn't any obvious abnormal growth or color but it did smell quite bad. Which leads me to believe there was some kind of biological contamination.

The auto pot itself had a crusties from the salts, but otherwise didn't smell or appear to have any biological growth. There was no flooding, but the tray did have water in it, while the rest of the trays where dry.

Not sure what caused it, but my guess is root rot. Just crazy how the plant went from looking perfectly happy to dead in 2 days. Lesson leared.

Yeah, that's fast.

Were you using the copper inserts? That is supposed to help kill the baddies and stop the roots from getting into the valve.

After a couple semi successful and one not so great grow - I gave up on the autopots. Great idea, not great for cannabis IMO.

Yeah had the copper insert in it.

This is the second run with the system. First run went good. Nothing amazing but it produced right at a pound and half off two moms we decided to test with.

This round was planned out a bit better. The other girls are looking wonderful just slight burnt tips but that was my fault. Guess time will tell.

He said his roots were clean when he pulled them but they smelled

Yeah roots were white still, but they had an off smell. Smelled like rotten eggs and wet earth. I bet if we had dug further into the root ball it would have been uglier but we didn't.

Other girls are still going strong.
