Hello folks
I been trying to grow plants for a months or two now seedlings are dying and all the time and, I dont know why.
Heres a pic:
Its in rock wool cube -amnesia haze.
It looks weak, couple of days old and i dont think its going to flourish.
What can i do? I water it, its under 250W MH lamp, with extractor fan. Set up is sound, yet seedlings are dying.
What shouldi do? Any help appreciated.
Let it dry out for awhile. Most common cause of “infant death” in seedlings is too much water, too little oxygen for the roots.

Just be patient, I recently had some seedlings stalled many days until they started to grow, now they are fine and healthy, yours don’t look bad at all … 
Sometimes when they are not growing on top they are growing on the bottom, rooting out. Seedling looks like its in good shape so far.

Are you using any nutrients?
Your wasting a lot of electric, for seedlings you only need a 10 watt at the wall, led light bulb at 12 inches away, I just use a desk lamp for the first 2 weeks.
As others have said, it looks good man, more patience and litfa is whats really needed, your killing them with kindness 
.
As mentioned above, overwatering is very common in newer growers. For the seedlings, you can get away with using a little clamp light or even desk lamp with a little CFL bulb. They dont require very much light to get going. Your little one doesnt look bad though. Just dont drown it, or put the MH light too close since it is a baby still.
Mine for example is a standard Daylight/6500k 23watt(100w equivalent on package) spiral/CFL bulb that I put in a round clamp light and does the job.
I’m sure there are other/even better alternatives, but I remember buying a 4 pack of these for my house for like 6 or 7 bucks years ago. Heres a picture for reference, the little thing on the right is an adapter that allows me to screw in an extra bulb if I wanted.
I like to have a light breeze on them too . I find it keeps the stems stronger
