Seedlings dying left right and centre

[DARKSIDER]

Any ideas what could be causing this to happen as im totally stumped just germed 27 seeds and they are dying on a daily basis have some under hps some under quantum boards and some more or less in the dark roots look like they are retracting on some others just last few days and shrivel some are in clay balls,, water running more or less 24 hours a day some in root riot cubes,, some in aero cloner,, humidity all in check ph in check ec in check lights at proper distances its got me beat so thought maybes get an answer or two over here cheers guys for any help the problem seeds are in my signature at the bottom for more photos if needed sweet seeds
First time this ever happened so got me beat. it looks like on some they have a membrane on them but upon closer looks it looks like rot deffinitley not a skin membrane..

A shot in the dark

Im thinking it could be some sort of rust fungi

Did you wash the seed's in h202 solution, before they where sprouted?

As you mention all your seedlings, are doing this under different conditions and in different enviroments.
That makes me think, it's very possible something that came with the seeds and infected the seedlings right away.

So how did you start your seeds?

Where they old, different strains, from different breeders or 27 seeds of the same batch?

 

[GOT_BUD?]

How exactly did you start them? Soak in water for 24 - 48, transfer to paper towel, then to ______________ medium?

Started in medium? Rockwool? Grow plugs? Soil?

What's your water source? Is it a clean source, i.e. not straight from the tap?

Thanks guys for looking in much appreciated as im totally stuck on this I know they will all die im 95 percent sure on that but what I need to understand is how it all started so I can stop it if it ever starts again if that makes sense been reading lots but still im at a standstill on this.

Q1.Did you wash the seed's in h202 solution, before they where sprouted?.. No..

Q2.So how did you start your seeds? .Some soaked in water some straight into root riot cubes and some straight into aerocloner neoprene.

Q3.Where they old, different strains, from different breeders or 27 seeds of the same batch?... All from same breeder 2 came as freebies,, and 25 came in little test tube,, as for age I did not check the package.. as I have never had a problem with these genetics in the past and have run them at least a dozen times over the years,

Q4..What's your water source? Is it a clean source, i.e. not straight from the tap.. Water source is from tap checked with my local water board nothing going on in my area to upset the conditions and I also have 8 cuttings in the aerocloner with nice white roots alongside some of these S.A.D. that's what I cannot understand

Q5 Rust fungi... A friend of mine said the same he said it looked like rust fungi spores.

did you remove the seedshell ? and the thin layer which covers the embrio?

 

[DARKSIDER]

did you remove the seedshell ? and the thin layer which covers the embrio?

Thanks WHIPEDMEAT for looking in but no never removed anything apart from the shell when it falls off into whatever,, here is a close up of one of the same seeds which you can see embryo is still on one of them but after a few days they just die its a new one to me.

 

[wh1p3dm34t]

i noticed that some of the seeds has hard time with that inner layer, if it is removed too early it hurts the seedlings surface, if it is not removed in time(too late) it kills the seedling somehow "strangles it"
maybe it tries to assimilate it ?

 

[puggle6]

Has to be some type of pathogen..

Maybe try and sterilize with h2o2

I had this one lately:

There are quite a few thread on here regarding damping off. Seedlings can look normal then suddenly start dying off for no other reason. Here is one:

[FONT=Arial, Helvetica, sans-serif]Damping off is the term used for a number of different fungus-caused ailments that can kill seeds or seedlings before or after they germinate.

[FONT=Arial, Helvetica, sans-serif]Damping-off can happen before seedlings emerge from the soil. With this type of damping-off, fungi infect seeds as they germinate. As the infection progresses, seeds rot and do not germinate, leading many home gardeners to think that the seed quality is poor. Another result of seedling infected damping-off is poor or weaker seedlings that become apparent days or weeks later.

It could be something else, but kinda sounds like a fungus. Keep us posted, I'm interested in how this comes out. Good luck.

Thanks for looking in guys and I will keep you all updated on this over the next few days or so but had another 3 deaths hours after typing on here,, So im now just going to put these down to being bad as my cuttings are doing ok nice white healthy roots,,, so whatever it is,, it is not affecting the cuttings in the aerocloner. Once again guys thanks for the advice Have read all your posts in the matter

The left cotyledons tip look it closer, that brown spot on the peak . that s a part of
necrosis usually starts from those on the cotyledons

I hate rockwool. Only tried it once and had problems.

I prefer soil as it's more forgiving.

i already have this case sometimes and yes if the membrane is not remove at time it strangle the baby and cause root rot .

lol thanks for the word.. "membrane " DD

Your medium looks too wet in the picture.

I don't know why people think they need all kinds of exotic media to sprout seeds or clone in.

Forget rockwool cubes, jiffy peat, etc.

Just put the clones or seeds in coco coir. Plain water for the clones until they root (leaf tips change color) and a low concentration of flowering food and epsom salt for the seedlings (0.4 EC BioSevia Bloom, 0.1 EC epsom salt).

Use a watering mat with a reservoir, and you can even do away with a humidity dome.

Damping off just kinda cuts them in half, they rot at a point on the stem. This looks like bad media or bad something or rather in the system/environment. I would scrap the lot and start anew.

Hope they weren't important genetics man it really does suck
