Seedling leaves turning (new grower)

Hi there. I have 4 seedlings about a week old 3 autos in 10L airpots and a zombie death fuck photoperiod in a small pot for now, under a MARS HYDRO ts1000 LED. All in bio bizz lightmix. Haven't gave any added nutrients yet. In the tent it's around 24 degree Celsius and around 60% humidity and I've got cut in half bottles over each for added humidity. Got an extraction fan on whilst lights running and put a small fan on for half an hour a few times through the day. The leaves seem pretty small and all but the photoperiod seems like the leaves are yellowing and turning instead of being straight, they're all currently growing there second lot of real leaves. I was just wondering if I'm doing something wrong or everything wrong? Any help will be appreciated. Thanks everyone, stay safe.
 
Take the bottles of them, seedlings dont need humidity like cut clones and can thrive in low humidity just fine like they manage to oudoors .

Thanks. I've taken the bottles off. It was 57% humidity in the tent when I've just taken them off. The leaves on the autos seem to be turning, maybe growing towards the reflection? Also yellowing, would bio bizz lightmix maybe be too hot a soil for auto seedlings?
 
I've moved the light closer as well. Around 24" from the seedlings now. There was no stretching anyway but just in case the leaves are rotating because of the light reflection and ill rotate them as the day goes on
 
Its not light reflectance its high humidity and lack of air that causes them to turn away from a bright light source.
 
Ok cool. Ill make sure I leave the extraction fan on and ill leave the fan inside on for longer than usual. Do you think the ts1000 maybe overkill for seedlings in a 2x2?
 
Possibly a ts1000 is overkill but i dont know its wattage or specs and not really much into leds. Im not happy with putting my plants in front of fans as more seems to stress them a lot, i prefer more my extraction to keep the tent and plants fresh.

Seedlings perfom badly when domed though so as soon as they break through the soil let them cope on their own and regulate their leaves as nature intended.

Maybe some others can help you with the light questions but there are some obvious things like not covering seedlings with bottles you can certainly know with confidence.
 
Ha they look terrible but will be ok for you if they bounce back in the next week. Look for good new growth ignore the bad leaves so far.
 
They don't look great. Currently between 25-27 Celsius, got it down to around 40% humidity. I am doing something wrong. first real leaves look kinda dry but new growth looks ok.
 
That's them. Hopefully they grow through it

Transferred a few to the greenhouse but the 2 I've kept in the tent the new growth looks a lot better. I think it might have been a mix of the light being too strong for seedlings and the soil maybe a tad too hot but they seem to have grown through it, hopefully.
 
A lot of soils are too hot for seedlings but they still work.

Most potting soil will sustain big plants with ease so very nutrient rich to start with.

Something to dial in on future germinations.

I'd ordered jiffy pellets to start the seedlings in but they didn't arrive in time so suppose it's down to my patience. Would have preferred to start in there then move it into the light mix. Suppose it's all experience!
