Does anyone else resize those things before posting them?

Anyway...

Hey Ande...start with a process of eliminating the probable causes.

Also...theres not much sense in using your warmer lights on the sprouts when you've cooler ones available. In the presence of the two colors, younglings will aim at the cooler light for it being the one that is more utilized for vegitative growth.

Are you usung nutes? If so...stop. Sprouts will get all the nutrient they need from what is already present in the soil. Get a different soil and see if you get the same result. Best to start with a soil that has a neutral pH. No adding nutes till they've hit 14 days.

What's the temp of the space? How close are the lights?

So yea, eliminate things that might be having that effect on them so you can pinpoint what exactly it is thats making things wilt over.

And sadly, genetics comes into play. Not all seedlings, even in ideal conditions, live to make it to the vegitative stage. If though this is a consistent occurence, likely theres something negative happening in the environment.
