auto purple kush leaves curling under.. please help

Hello all. I have here my auto purple kush pant. Its 17 days from seed. It has pistils showing already . My leaves are curling under. I did do a very rookie move an spray a lil nute juice on them not realizing it was in the spray bottle. Im running @ mh 400 watt light on 20/4. Temps are at a steady 75°\85°. Ph run off was 6.5 this afternoon...I also have an ww x og kush 6 days from seed loving the grow room....

Looks nice that's quick to show sex

Looks good. Maybe a little too much water.

Damn that thing started preflower quick, flowering nutes help speed that process up. Its prob just a little to much N, mine had the same issue really bright new growth and curled tips (also known as claw shaped) but are doing perfectly fine. I believe its a non issue on gl on the rest of your grow.
