Hello guys,

I got this seedling that is stretching and having these burnt tips.
I'm using BioBizz Light-Mix and some homemade compost (which is probably the problem) as the medium.
I use 240 watt Kingbrite LM301H epistar lights at 50cm away from canopy at around 38%. I kept it before at around 45%.
Any idea what could cause this? I could provide more info on my setup if needed.
Is this nothing that bad to worry about? Let me know!

This is why I fill the solo cups about 3/4 full after they are saturated when I plant seeds, so I can top fill if the seedlings stretch like crazy. The light seems sufficient for such a young seeding, so I don't think you need more light, it's just genetics. I would either put some soil around the stem to help prop it up or use a stick to tie around and prop up the seedling.
