Is this Normal.?

Hi everyone it Been a while since I posted anything..
I have this Og Kush that in F.F. Ocean Forest soil and she about 1 1/2 months old and under 400 watt Mh 18/6 3x3x6 room good exhaust and intake good.
water Ph 6.70
Barely started feed with F.F. Grow Big.
Temp 80 day/night down to 50
So any help why the leafs are curling inward around as you can see in the pix.
Is this normal.?

Hang on have to resize the pix when I get back

Your temps are changing too dramatically. Don't let them change more than 10 to 15 degrees max. and thats for only a couple days. try to keep them constant. It stresses the plants out.

Here the pix but the size might be small..
Hope you can see it

Thanks!! I'll set my heater up tonight for the next few nights.

I enlarged that pic to take a closer look, and is sure does look like some pollen sacs there. Are you positive that it's a female?
