Seedlings HELP!!!

Learn everyday, otherwise you stagnate. I had to open more vents on my tent because of the heat. But good for noticing. Keep us posted

Yeah will do.
It’s been unseasonably hot here too so I think this will help cooling things down as well.

It's highly doubtful that the vent had anything to do with whatever you are worried about. There is plenty of ambient Co2 in the air. Even if that tent was airtight it would take weeks or more for 3 freshly sprouted seedlings to use up what was already in the tent.

I get what you’re saying. I mean each time I opened the tent I’m effectively replenishing the air, but with it flowing now it feels like a much healthier environment for them, and the heat is dissipating better, air doesn’t feel as stagnant in the room feeding the tent.
They got a bit bigger too. It probably was the watering or whatever but decent airflow can only be a good thing.
Also switching to 18/6 I think they benefitted from a bit of rest from the light, I know they can take it but I still think they have.
Cheers.

I've run 20&4 to push my autos, but like you, I feel they benefit from a rest period. Can they handle it, yes. Should they have to? That's on the grower.

Update.
Well, I’ve taken onboard the advice given here and I’m determined to be patient not love my plants to death.
However, they are autos and I want to minimise mistakes so I don’t get stunned plants. So I’m still worrying about them. Haha

So one of my seedlings has very shrivelled, first couple of leaves but new growth looks healthy.
The conditions have been exactly the same so could it just be a bit of sickly, runt, plant?

I realised the PAR level was too high. So I put my lights down from 80% to 40%…errrm yeah.
I was frying them….. a bit.
They weren’t burnt or dry though, and they’ve all been getting the same so doesn’t account for the one droopy one?
