need a bit more info like temp. and humidity
looks like heat wilting to me
also was this right after lights on > its normal for plants to wilt like this when the lights are off and they perk up after the lights are on for a bit
Although sometimes you'll see flowering plants droop..The excessive green (maybe my eyes) looks like something I was reading about in FAQ...to plant prob....to nute/ph prob. to chart by Nietzsche.... check it out...they my be fine..and just my eyes.
when was its later watering ? i ask cuz see my pic of my plant looking bad ... well it needed a watering bad !!! it was in like its 2 week of flowering atm maybe the 2nd and 3rd pic are 2 days after i watered it GL friend . Oh also my grows outdoors if that makes any difference and live in the south so its really really hot here
