Need help with seedlings!

I planted a bunch of seeds in rockwool and put them in a propagation dome to sprout. I checked on them constantly and all of the 22 seeds sprouted, but after 3 days, i noticed an odd mildew smell when i opened the dome. Apparently i didn't give them enough ventilation and one of them actually died from what appeared to be rot. I took the dome off immediately and i now have them under a T5 fluorescent hoping they all don't die. Can anyone suggest anything to help me save them?

I only have given them water that was 5.5 ph, nothing else.

Make sure you have a fan in your grow area, keep on low to ventilate the area, but do not aim it directly at the plants.
Continue to give them water as usual and you should be in the clear in no time

Pictures would be very helpful.

Here's the pic i took of them when i first planted all of the seeds. Most of them are roughly an inch tall now with their initial two leaves.

At this point, i have all of the rockwool pieces sitting on top of the tray so that they can dry a little bit and hopefully get rid of the moisture causing this rot.

Other than a very very light ventilation breeze... I think you're doing what you can

I've had a small fan sitting about 4 feet from them, blowing the opposite direction, so the air around them is constantly moving. Seems that they've all died or are in the process of dying. Checked on them this morning and they all look like they're shriveling up. Pretty frustrating that there is nothing more i can do...

at that young age be very careful with watering. the dome will hold in the humidity and watering too much is easily done. when the seedlings are that young i use a mist bottle for watering just enough to keep them slightly damp. GL

and if your PH in your water was off they sometimes just stop growing after sprouting

I checked the ph in the water I was giving them and it had creeped up to 6.8. I made some new 5.5ph water and gave them a bit. Is there any chance theyll pull through? There doesn't appear to be any new growth...

So, i stuck with it and after i aired out the rockwool and gave the seedlings 5.5ph water (with a few drops of root stimulant mixed in) for 4 days, they FINALLY seem to be making a recovery. All root growth seems to have really picked back up because i can see several new healthy white roots on the bottom of each piece of rockwool. All of the leaves seem to have perked back up as well. Thank you for all of the suggestions, gents. It really helped.

Ya if there's moisture in the dome like where its beading off the plastic they'll recover. You should just be ok keeping the dome on and having your floros right over it. Those seedlings love the humidity and I think the light is what keeps mold and mildew away, does for me anyway the only time I open the dome is to water. Mine like to be wet they like plenty of water from my experience and the one time I did back off water with a seedling it almost died. Basically they like a wet humid environment with good floro type of light. Keep them in that and I guarantee they'll make a full recovery.
