I've noticed that two of the girls I flipped last week are displaying some leaves that are curling down. I couldn't get the picture to upload here, but click this question and you will see. Any suggestions? Thanks.
Yoo bro! Looks like it could be either overwatered ( wouldn’t worry on watering if you using coco), but it could also be a nitrogen toxicity depending on what you gave her. Last thing i would check is air. Is your plant having a fan blowing on her constantly? could be stressed from this. Good luck with it man 🖖🏽
