If she is surrounded by other plants, are you sure she is getting enough sunlight? From what I have learned, they need lots of light.....

Stick your finger in the soil (not ontop of the roots though) - see if its wet or dry. that should tell you what to do. If its super dry, then she just wants some water, I dont think you will be able to judge based on other plants, because I have a whole garden or veggies, and NOTHING is like my MJ plants....:smokin:
