Babies have bottom leaf curling down, brown spots

Purple punch auto, been under 24 hours of light as I'm apparently too dumb to figure out my timer, fox farm ocean forest with natures living soil autoflower mix, mixed into bottom 1/3rd of pots, Temps are 73 f, 44% rh.

I have been spritzing them once a day with water that hasn't been brought up to temp (spray bottle outside the tent) also the LED's were on full power, I dimmed to 80% today. What do you guys think, help me please??

1. I would figure out the timer. Set to 18/6
2. Raise those lights up to at least 24-36 in.mine would be at 40inch but no dimmer on mine.
3 don’t need to be misting. Just water around the plant. Personally I would water the whole pot every 3 days. Do need to add any nutrients right now as well. Raise the temp up to 79-80

Improper watering..

Alright, raising the lights up, back to 100% each, no more spritzing, and I thought the temp was a bit low, but I have a buddy who works at a cultivation facility telling me the temp was perfect. This is my first grow in like 4 years, and first grow with LEDs ever too.

Yeah, I had issues with this soil getting so dried out, it was arrid, I tried to water around the outside of the babies, but the water was causing the soil to be displaced, I'm definitely starting in smaller pots next cycle and transplanting. I really appreciate the help though guys, thanks a lot man!
