Seedling in RW Cube - Wiling - Damping off?

Solo Cups, about 2" of perlite then placed a RW cube on top. Cube gets a few drops of water every night.

5.9PH water
75.92F (24.4C)
54% RH (in Room)
a little higher % RH for the seedling as they are in a tray with a dome half open.
Under one Regular household CFL.

Two dropped dead =( .. I really wanted these seeds! Other one or two seem to start to flop over. Rest are okay.

What should I do, as the temperature and rh seem within reasonable range? Then what would be the problem?

Id loose the dome..ive never seen a need for a dome up air circulation small fan nothing crazy just move the air..its where id start everything else seems fine keep that light close to limit stretch ..gl

Too much moisture.
Light not close enough.
I found it better to remove the humidity dome once they break the surface. My environment is nearly identical to yours.
I start mine with a 4 bulb T8 fixture at around a foot and lower it to 5-6" once they break surface and start growing up.

Thanks guys!

It's at temp-setup until I can get things ready. Figured I'd pop the beans and let them start getting some root structure. Lamp is as close as I can get it, maybe I'll see if I can prop them up a little bit.

I need some T5's or 8's for veg... or maybe just build a small veg led setup eventually.

If you're in the US, lowes has a really good deal on this 2ft T8 light right now, you just have to follow the directions to wire a power cord into it yourself.
It uses 2 u-bend bulbs so its like a 4 tube.
They had some cheap bulbs on the clearance rack too i got 3 for like $8

I looked at lights in local sell groups, letgo, craigslist ect... and there were a lot of T5s and T8s for sale, but the cheap options were $50+
This one fit perfectly under my table. Just took one of the 3 shelves out from under it and made a little germination shelf.
The bulbs werent the best (new good ones are ~$10 each) but i was plenty happy with it for a $26 seedling light.
