I recently propagated a new pothos plant from stems cut from an older plant. I put the stem cuttings in water for about two weeks until roots came out. I've done this several times, always successfully. This time around, the plant looks unhappy. The leaves are limp and curled. It has been about three weeks since I've potted it and no improvement. I've followed the same process as previous occasions - similar soil, same pot, same watering schedule. I wonder if the issue could be that I'm repotting in fall, when perhaps spring would have been better. From the picture, does it look like I'm over-watering? Under-watering?
