Leaves pointing up

[spysmasherr]

Have 5 plants ready to go to flowering. All have been healthy growing in a 3 gal pot with very old horse manure mixed with worm casings, potting soil, vermiculite and a bit of lime. One plant all on it's own started having the leaves pointing up as opposed to the normal position of fanning out and laying flat. Two bottom leaves started curling in showing distress. Repotted today and gave it a good watering. Any clues to what is going on? No browning of leaves or drying. This is my 1st forage to indoor growing. Have some great harvest out in the woods before. Thanks...

Can you post a picture? That will help identify the problem a lot better

Yes. I had this problem my first grow. My exhaust fan went out and I didn't realize it, and they did as you described. They need fresh air!
