need help urgently (with pics)

basically i have 2 plants that have been flowering for two weeks they have both been fine but recently the leaves have started to curl down and become twisted could this be a problem with water or light? the flowers still look good and they are still growing in height at a constant rate. i use a 600w dual spectrum bulb with an oscialating fan running 24/7 they get 12 hours light a day and the temp in the room is around 90 degrees f in day and 80-85 at night any1 have any ideas?

also i have some supergirls that have been grown hydroponically for 2 weeks they look a little small to me and was just wondering if any body had any comments on them they see 18 hours light a day and are watered twice a day for a minuite a time using a drip system and rockwool cubes any tips or ideas?

with those temps, i'd say you've got heat stress. my babies get stressed anytime they go over 85...

would that cause them to tiwst an curl? i heard leaves curling down was a water problem or is that jus a cannabis myth? and if that is the problem what temp is the best for flowering?

I've heard 75-85 is best for flowering
