Not sure. I have a hybrid indica that contorted it's 7 fingered fan leaves toward the light it chooses and a droopster. So I watch the jagged edges on the leaves. When they stop pointing up, it needs H2O. My Various CBD, 70% ish sativa hybrid. All the leaves droop. That's the way it is. The jagged edges point up when productive and not when it's thirsty. If that fails...Lift it, wiegh it, stick your finger in there and hey how about a moisture meter. If all this fails me; ...I...Am...stupid. I should not be growing anything except maybe dandelions but under heavy supervision. Still, I believe that keeping a detailed list of events will keep things moving in a forward direction. Not even a poor memory from head trauma will fail provide I right shit down.
