Little bit of leave curling

This is Auto Skywalker Haze from dutch passion. It'd been 16 days since she popped out of the soil. I've noticed a some of the leaves at the bottom curling downwards. Would this be from wind burn? I did have the fan a bit close and it seems to be the leaves that was nearest the fan. I've moved the fan today. Otherwise I think she looks healthy?
If you notice white spots on the leaves it appeared after my clumsy watering.
