Answer: Well, you've got me stumped. It is possible there is some insect activity there such as aphids, so have a close look for that. Next, in some cases seedlings will curl a bit in response to foliar feeding, so make sure you are diluting any fertilizer adequately. Next, make sure that they are rooting into the medium as they should. If transplanted into a medium that is too dry or otherwise unsuitable, they may fail to root adequately. Last, make sure that you are using all clean materials, equipment and relatively sterile soilless mix. I hope this helps you figure out what is happening.
