New grower looking for info on seedlings

[rats]

Hi all this is my first grow and I've got 4 seedlings that popped up. I Planted the seeds directly in rapid rooter soaked in very light mixture of clonex solution and water, I also sprinkled myco in the hole.
Planted 11/13 at 8pm and they were all out of the plug by early afternoon on 11/16.
They're all about 1.5 inches but one of them is 1/2 inch taller than the rest, I think it's because it sprouted over night before I had the lights on.

Using ACI humidity dome and 2 S16 lights at level 5. Yesterday the photone app said it was 250-300ppfd today it's showing 400+ so I don't know what to believe. The lights themselves are actively pulling 13 watts combined. Temps have been between 70-80f and 60-75% RH, I used the heating pad the first 2 days to help keep temps more consistent around 78°.

I'm seeing roots on the one the sprouted first so I'm assuming they're healthy and I'm probably overthinking it but how are these looking? Are the leaves curling down telling me It's too much light?

They look good! I put the plugs in soil when I see a tap root coming out the bottom. It looks like you're using the same equipment I do, including the plugs. I've had very good results with it.

Are the leaves curling down telling me It's too much light?

Downward curling is common for the cotyledons. The light level is probably okay.

That's great thank you! I take care of a handful of very happy tropical houseplants but I've never grown anything from a seed so I I wasn't sure.

Is the bigger root at the bottom right the tap root?

Hi all these are 8 days after sprouting just wondering if this is what wind burn looks like on seedlings. I'm not too worried about it as new growth looks healthy but just want to know for next time.
