what strain is it ? if its all sorts of strains you got yourself a issue .
if its just one strain then pull the mutants . how many is there?

definitely need sort that light out and more than likely start fresh lot perhaps ? since you aren't too committed into them ?

It's a bunch of strains, all strains are hit by whatever this is. I am thinking is some sort of fungus or some shit, cause it was really hot and humid in the greenhouse when I moved them in, then it became cloudy and chilly... and I have a few FAK's going on, started in the same dirt that are fine. Truth be told, there's some weird leave curling going on there too, but nothing major at all.

Thing with the light was that I don't have space in the grow room, I saw it wasn't working well, so I took them out in the greenhouse and it's been pretty cloudy since...

That was my earlier batch, like 180 seedlings or so, I'd say good 80% are hit. I am gonna take out my mother plants out as soon as the weather allows and start a new lot in the grow room and adjust the light. I'll sterilize the soil in the microwave this time...

The only thing different that I done here is I added microelements to the mix. But what bothers me is that nobody seems to know what's happening here. So I am a bit nervous.

hate to be the one to say it, but maybee scope for broads or cyclamens. mine looked alot like yours.

[Purple Jungle]

Lochinvar, I didn't really get you, could you explain? So you have the same issue going on too?

high grade seed raising mix mate , i checked what your using in your thread . i wouldn't be raising my seedlings in it .

yep restart , not the end of the world . good luck

You shouldnt need to sterilize your soil.
Ide start over with much better soil, like a 50/50 mix of Light Warrior mixed with HappyFrog. Then up-pot to 1gln pots of HappyFrog. Then up-pot to Ocean Forest soil when they get rootbound in the 1gln pots.

I agree with Overgrow, start over with his recommendation.

I think your issue is soil related, possibly a virus in the soil.

I once had a bunch of seedlings that looked like yours but were older (3-4 weeks) turns out in my case it was thrips.

How much (volume) of soil are they in? I just had an issue with sprouting in a tray. solved it by putting them into solo cups. seems there is a minimum amount to soil they require...

Sucks ur having issues w the seedlings.hope you get it sorted and continue on. I'm having issues starting seeds outdoors at about 42n due to cold night time temps still in may, and fungus gnat larvae. I will also be running dozens of varieties outdoors including fire alien kush f2 and a bunch of others. I'm subscribed to see how ya do. Good luck and I wish u a bountiful harvest in the fall.

I have seen similar weirdness with a application of worm tea on tomato plants !
