lack of phosphorus???

After searching Jorge's Bible, i would guess it could be a problem with nutes!!! Could something else make leafes curl down??? Heat???
Apreciate any help!!!

Heat, overnute, suffocation and/or diseases of roots, abnormal ph, overwatering, underwatering, too much nitrogen among other things.

Since we have no idea what conditions you are growing it's pretty impossible to say.

Good luck.

among your other possibilities, you are due for a larger container ... watch the over-watering, too ... (P.S. - half of what I've read of Jorge Cervantes, suggests he is full of shit) ... :jointsmile:

Your medium appears a little dry to me. They look thirsty.
