Technical Issue First Grow - Seedlings fell over-Light too far away?Help needed.

[1nf1n1ty]

I've been growing 2 Dutch passion Auto Banana Blaze but I only have a 600 HPS and I didn't want to put the light too close and the seedlings looked healthy yesterday
but I've just checked them and they both fell over in the night, I don't really know if the humidity is too low or because I left an outtake fan on when the light was off or if it's just the light was too far away, but its a 600 and thought it would be powerful enough at about a meter away.

Heres some pics, one taken 10pm last night and the new one taken 10pm tonight (an hour ago) any help greatly appreciated. Gutted

I also noticed the leaves went up (instead of drooping) and you can kinda see it in the 2nd pic.

It's very common to have seedlings fall over like that, and usually no harm results.
You've probably killed the sprout pictured in your hand, but replanting it might work.
About half of mine fall over, so I just use small stakes to upright them.
The stalk will fatten and straighten if supported.
Some people like to bury the stem.
Seedlings can have strange appearance and behavior.

well i buried the them deeper and lowered the light a lot, now im worried it might be too low, it gives off a bit of heat, but ive got a big oscillating
circulation fan blowing right at the light and fabric pots.

thanks for the reply.
