seedling problem

out of 5 seeds 3 have sprouted and showing 4 leaves but one has its largest set of leaves curling downwards and almost touching the stem.

they are under 3 twin 58w floros with humidity around 35% and until a few hours ago were around 1 and 3/4 inches from the lights now are just over 2 inch. i thought this might be lack of water but the soil surface is slightly damp they were saturated when planted 2 days ago they are planted in bio biz all mix if this helps and other 2 sprouts seem fine.

any help appreciated cheers

 

are the leaves firm? or do they feel weak? if they are firm then it is prolly overwatering, weak feeling is underwatering.

 

aye leaves are firm, stupid me went up n checked on em this morning felt the soil n thought aye il give em a good misting and done so then came on here n found out its prolly overwatering. just have to wait n see how it does, cheers for the advice.

 

Sounds overwatered to me too. The misting won't do much harm though. Small plants take a while to use the moisture in even a small pot.
