leaf edges curling up but no yellowing

they r on week 2, 3 days in.

so i got leaf edge's curling upward but the plant looks healthy heres sum pics my plant is under a 150 watt hps in light warror soil i did raise the light up to 11inch right before i posted this so what do u all think?when should i raise light or lower it?and if i have to raise or lower by how much?

What is your PH?

I would say your light was to close and the seedling was to hot.

Everything looks good to me. It doesnt look to hot.

my water ph is 6.7 and for the heat i can drop it to 8 inches and just alittle heat comes off of it

is 11 inches to high cuz i dont want my plants to strech much

I'd say if the plant isn't too hot it just needs water. Usually when I see leaf edges curl up like that it is because of heat or respiration stress.
