Looks like a little over or under watering stress. Those leaves should not be drooping like that, so if you have been watering it a lot, you need to cut back. If you have not watered it in a few days, then you need to do so. Both stresses look very similar.
Also, that plant is a juvenile. It may be flowering, but just barely, so you have at least 5 weeks, perhaps more ahead of you depending on whether this plant is a sativa or indica dominant. If the plant is getting direct light for 5 or more hours, then that is enough for it to continue to grow.
The biggest issue for you is going to be temps if this plant is outside. You will need to move it indoors at night to keep it from getting killed by the cold night time temperatures.
Hope I helped!
