m0useanswered grow question a year ago Limp Leaves & Stiff Petiole "leaf stem"= Over Watered
Limp Leaves & Limp Petiole = Underwatered
I find underwatering will be extra limp and almost deflated like,
Resting cannabis leaves point down like overwatered but will perk back up when they get more light, if its overcast they may stay sad looking.
If growing in soil aeration is good, I have had some grows go back from lack of aeration and the soil compacting to much then root rot and it makes the leaves go brown and yellow crispy and fall off. sometimes they crisp up when they are green.
Good Luck!
