Flowers curling oddly

Had a question, the leaves around the flower seem to be curling oddly and I don't know why...
they're almost done flowering probably about two weeks left but here lately the leaves are curling oddly
and I can't see why... Any ideas?

how big is the pot you're in? I have a similar problem and I think it may be due to moisture stress, and mine are all in small pots.

Hard to tell, pic 2 does look like a possible overwater situation to me but again, hard to see.

I think you have more than two weeks to go before she's done. What strain?

It's a 3 gal pot. I alternate between nute and plain water every 2 days.
And it's White Castle strain.. According to time period if the strain I'm about 2 weeks away.
Everyday she fills up with more and more crystals, and she smells horrid.

This is the full plant, she had a slight nute burn about ten days ago as I accidentally fed nute water twice.It's under a 400w HPS and on a 12/12 with complete darkness at night.
Humidity is about 47-49% and temps stay about 77-80 degrees and has good air flow.


She's a tester for me as I'm a fairly ok gardener so I only did two to see how I am at it.
My first one died from accidental over nute, and this one flipped flower after only 9-10" tall.
Doesn't look like it but she's actually around 3.5 feet tall.

Let it dry out a little more between waterings.

It looks like it could use another month or so to ripen up.
