Eucalyptus Deglupta (Rainbow Eucalyptus) Germination Issues

Hello there,
So I've recently been interested in growing a few rainbow eucalyptus trees to make into bonsais or grow into large indoor plants. Unfortunately, every time I attempt to grow the seeds, they die at the exact same point.

I've germinated 3 groups of seeds: one in regular soil, one with an extremely diluted amount of miracle grow, and the third with oxygenated water (from a low concentration of hydrogen peroxide). I don't go crazy with miracle grow or hydrogen peroxide...especially while sprouting seeds.

EACH TIME they sprout after a week or two, grow for about 8 days, and then die. All of them. I can't figure out why in the world this happens. Perhaps the soil I'm using is not conducive to seedling growth? A high humidity and a reliable, warm temperature was always kept. It's just odd that about the same time of death for ALL seedlings has been consistent.

any suggestions?

    Have you tried any in a gritty compost? No extras. 

    Seeds don't need fertilizer, and if you've got an open compost there'll be plenty of oxygen. They may have over-eaten and got indigestion

    In Australia, I have seen eucalyptus germinating in very sandy free draining soil, low nutrient levels, and low humidity. 

    It's not a mess, it's a nature reserve.

    Very beautiful tree, found in Hawaii, not Australia. Is Hawaii very humid?

    Are they damping off with high humidity?if so a fungicidal spray may help.
