When was it last perky and what did you do between then and now? Just at a glance it seems like it's hot in that space, or you have lower than ideal humidity, or both. Usually a droopy plant like that can occur from over watering. How wet is your soil? There could be a deeper problem going on, and by that i mean something at the root level.

Is that pot heavy when you lift it? Over watering is so common with new growers it's almost a given. You appear to have some pH issues goin on as well. Basically it's something under the soil line that's the issue and it's likely oxygen starved roots, a touch of root rot goin on (big maybe) but i'm sure your pH is goofy in your soil. Hit me up on discord and we can voice chat and get into the nitty gritty of your grow and see what we can figure out what it is and the course of action to take to bounce her back.
