Yeah it was but it stopped the root rot and didn't do any real damage to the plants, they looked fine all the time during the treatments and they lived. I'm sure it stopped them growing for a bit, the harvest won't be what I'd wanted but that was a better outcome than them all dieing from Root...

Yeah a bunch I'm pretty sure that's the scientific measurement. Oh OK it was about 3-4 grams of 32% calcium hypochlorite in about 80 liters of water. Well it was root rot but that contains 5 different fungi so specifically I don't Know what it was, the plants were wilted like they weren't...

Hey thanks, yeah that's what I thought. So if I clean it all out and change the res keep the environment good, what do you think of putting some new plants in to flower with the remaining ones that have survived? I'm a bit hesitant to do that, them staying alive is one thing but I'm wondering...

Hey thanks but ec isn't too high, 1.8 and 2.0 is a good level for that time in flowering, I think 0.9 is super low actually. Yes I was totally watering too much though for sure, and the ambient temps here during lights off for like 3 weeks made the water get up to 22/23 degrees celcius, I knew...

Thanks bro. No there's no powdery mildew, might be a dried leaf, even the dried leaves are bone dry crispy I've got the mositure down so low. The finish will be diminished of course but yeah not a total loss and I learned something.

A week later. Their growth is a bit slowed for sure and I'm not expecting a huge yeild but they aren't dieing and these were in the same water and flood tables as the ones that died.

Hello so I've had root rot now for the first time, a flood and drain system. I'm wondering though do all the fungi that cause it, Pythium, Phytophthora, Rhizoctonia, Botrytis, Alternaria, Fusarium exist all around us anyways but it's just giving then the conditions to take hold that creates the...

Hello I'm having some root problems in a flood and drain system, my first time, and it's killing my plants one at a time, they'd roping fast. I can't get any h2o2 right now but I do have 32% calcium hypochlorite. I've already put about 4 grams in a 75 liter res and fed the plants for one 12 hour...

Man they going down one at a time, but the roots aren't too bad, they a bit off colour but they don't smell hardly at all, just a bit right up close, the roots are still firm there's no slime, but for sure the plants are checking out. How much h202 is too much? Like if I mixed up a strong mix...

They were healthy white before, they aren't slimey though, but yeah something going on there, that plant is a goner, was so nice. So I could change the res but what if I used some additive also? I hear physan 20 is good but I can't get that where I am. What if I turned the res temp way down...

Ah thanks. Yes I see the damping off looks the same on a grown plant as a seedling, but the stems on my plants that have died are healthy and hard.

I see what u mean but the stems don't seem weak at all, I've seen damping off alot in seedlings, I'll check later. I pulled the 2 dead ones out ages ago and the stems weren't deseased like a damping off infection, it's the leaves and new growth that wilts, stems are rigid, but I will look

I'll take some of the healthy ones I don't have any of the dieing ones previous to being this way.

How does it manifest in older plants, what's it look like? I couldn't find any info on that.

It take about 12 minutes to drain hmm you think they not getting enough air, hmm, this is my first flood and drain, yes maybe hey, that might be too much but they look really healthy for 4 weeks with the same schedule so why suddenly start Nothing liking it? Like they were all doing great.

Damping off in full grown plants? I thought that was only for seedlings. I'll check that. Nothing I can do about the heat atm, I've had high temps before though it never did this.

What about the fact the pistils turn brown? Could that be some sort of indicator of something or would they just go that way because they're dieing?

Bare into the hydroton in pots.

Thanks hope to figure it out.

Yes I looked at the roots they looked OK to me I'll look later, what specifically am i looking for? They aren't slimey or black or falling apart, well not when i checked the one that died. .
