HELP plant starting to act strange

When i woke this morning noticed a little browning on the edge of the leaf just got home from work and plant has gone like straight in the air almost like its trying to close in on its self. they were a little dry so i watered them really well what would cause the plant to brown in the first place and then to close up on its self? no nutes yet planted in foxfarm ocean forest soil in a 3" planting cup they are about 12 days old

it got hot today as well does this have anything to do with it?

What type of light? Mine did the same thing. I just moved the light down a little and the leaves went back down. not sure about the heat tho..

its 3 t5 light the plant was kinda wrapped up and around the fixture like hugging it

spooky.........

just pull it up a little then
