Day 2 seedling light issue?

RF90 · Dec 15, 2021

Hey guys so this auto sprouted yesterday. I have two 24watt t5’s hanging 8 inches above it and two 23 watt CFLs about 8 inches to the side of it. 24/0. Also I have a humidity dome on top keeping it at about 60% RH. Temps ranging from 70-80. It looks like the first true leaves are purple/brown? Do you think the light is burning them?

this is my first grow with t5 or CFLs. I usually use led.

Thank you!
All advice welcome.

No dome. Dampening off will occur. What is that medium? And just the single T5 a couple inches above is sufficient for now.

My opinion is you've domed it a wee bit too long and it should grow and green-up now that it can bteathe.

Seed starting mix about a solo cup deep. Outside of that is FFOF

Taking off the dome will that stop the dampening?

Looks nute burned. Light bleaching doesn't appear like that.

Yes. No dome once they emerge.

So 45% RH no dome is better than 60% RH with dome?

Yes. Once dampening occurs it dies. There's no saving it.
