Top leaves clawwing down

Hey, I'm having an issue with my plants that I was hoping maybe someone on here could help me with. Unfortunately, I have no way to get the pictures onto my comp, but it's pretty easy to picture...I hope lol.

All the little leaves at the top of each cola on only one plant have curled in, look like claws, half of them have twisted around and spiraled, but they are all very green. It is only the very top leaves as well, none of the other fan leaves have done this. She has been flowering now for 3 weeks, and im using CFL's, so I don't think heat is a problem. 2 of the colas are higher than the other 2, so I don't think the position of the lights are a problem either. I was thinking maybe the fan was too high, so I turned one of them off so the wind was only coming from one direction, and nothing changed after 24 hours.

I did spray all my plants with Neem Oil right before this happened, but it's only the one plant that is doing this (I sprayed fairly young clones with the Neem as well, and no problems). I just flushed the plant thinking maybe it was an over-fert issue, but I guess I guess I won't get any feedback on that for a little while.

Anyways, I was curious if anyone has ever had a problem like this before and what they might have done to remedy it. I'm just using soil, with a little bit of DNF for flowering on her. Any suggestions? Please???

Light leaks during the dark cycle can cause leaves to spiral,start there and check nutes next.

seriously? i had never heard that before. makes sense though, as i go in the room often to investigate, but the light that sneaks in is so negligible, and i have a green bulb in the room itself. thanks for the advice, im definitely gonna watch out for that.

i was thinking that maybe the neem was too strong in respect to N, as the leaves are really dark green, and shes been flowering for 3 weeks, hardly any yellowing at all. im gonna try and get pics.

but again, thank you so much for taking the time to offer some help. very appreciated!

What's your ph of your water? How did you mix the neem?

Sounds like an Nitrogen overdose too me. But no way to be sure without pics........

i put 5ml of neem and 2ml of a wetting agent in 1L of water and sprayed the hell outta them. im not sure the pH, but ive never had a problem like this before. i wish my phone would upload to the computer, but my comp doesnt seem to like samsung phones lol
