Hey hey... What kind of soil do you use? How close do you keep the lamp? And they look like to be around 5-9 days old so its possible something happen around this time. Are you sure you just gave them 1/4 strength nutrients? What nutrients and dose?

 

[Wait what?]

How hot is it in there? Looks like heat stress, but the pics are glarey, so it's a little hard to tell

Sorry I meant there were planted 3 weeks ago I'm using biobizz all mix soil I checked the recommend dose and give it 1/4 of that and i haven't got round to getting a thermometer yet but it is really hot in the tent I have a fan going

Heat, maybe, but looks a lot like nute burn to me.
As Tdam said, what kind of soil? And what nutes did you feed? Autos can be pretty touchy with nutes, and these look under age for strong drink.
I'm thinking nute burn because ia at least one or two pics it looks like the damage is starting low and moving upwards.
Edit: what are your temps?

Its a strong soil.. Ec of 2.4. ( used google) and you gave them some extra nutrients aswell. So this is probably the problem. Redneck.. What can he do to save the situation?

I hate to advise a flush on young plants like this, but it looks like they're burning up.
I'd give pHed water, (SLOWLY!), at least equivalent to pot size, just to get the worst of the nitrogen below the root system. Then let the soil dry. The water will release more N from the soil, but hopefully will move the biggest concentration south.
And pray.
:karma Cloud: for your gals, friend.

I agree on the overfeeding. That All Mix is considered a "hot" soil because of the high amount of organic nutrients it contains. Autos seedlings generally don't like hot mixes. Next grow I'd suggest you either start them in some Light Mix then either transplant or use the tiered method. Or hollow out the center of the All Mix and fill it with Light Mix. The seedling will have time to get started in the cooler mix and grow out into the hot mix as it gets more mature. The All Mix has enough nutrients that no extra feedings are needed until it's about a month old.

Do yous think I should start over or should I flush them
