first time grower, slight leaf curl

Hello all, sorry to post about something I've already been able to find a little bit of information on but I'm hoping with some specific information about my grow and some detailed pictures I can get a point in the best direction. I have some moderate leaf curl, which I've read could be from too close to the light (trying to hide), too far from the light (trying to reach), too low humidity (drying up), low magnesium, too much fertilization and probably some other things. Given these two pictures, would any experts have a suggestion as to a "first stab" at fixing these curls? Overall the plant looks, IMO, very healthy other than the curls, but as a first time grower I certainly do not have a trained eye. Humidity is at about 60%, temp is a tad warm - about 80 degrees in the room, 84-86 on the floor directly under the light. It does not feel "too hot" under the light though. Light is roughly one foot away from the top, 400 watt HPS. I have only added fertilizer twice thus far - the plant is roughly 3 weeks old. On the closeup, you can see a small discolored marking on one leaf, but I don't see that anywhere else on the plant so I'm willing to overlook that at the moment.

Side note: I water directly into the soil, should I also be adding water via misting, etc. to the leaves?

Thanks for any advice in advance, I can take more pics if helpful. And in case anyone is curious, its an autoflowering white dwarf

Heat stress, back your light off... I didn't even have to read what you wrote

heat stress lol

Back your light off when you mist it also. And unless your foliar feeding then there is really not much of a benefit to misting your plants

you should not mist your plants unless you are foliar feeding the water magnifies light and could burn your plants and it will increase humidity in your room can create powdery mildew etc.

Perfect, thanks for the quick responses guys. I've raised the light about a foot, kicked the fan up a notch, and will let the room cool a bit before turning the light back on in the morning. Thanks again

Just in case anyone comes here while researching, heat stress did turn out to be the issue - backing the light off, cooling the room a bit and letting it rest without light for a night gave signs of improvement overnight. I had seen other posts where people were asking if their light was too close and some would swear up and down it is impossible to get too much light, and while that may or may not be true, you absolutely can give your plant too much heat as a result of being very close to the light.
