Don't mean to be harsh, but you needed to do research long before you thought about buying a mature plant.
Read the stickies in the 'Newbie' section, then head over to
http://www.growweedeasy.com and peep the 'The Basics' section.
Research quickly, so when you do need to ask questions, they are relatively specific and have meaning.
Again, don't mean to be disrespectful, but generic, blanket-type questions won't yield positive response.
"How can I help her?"... first, state your soil/medium, environment, lights etc. Is this an outdoor or indoor grow? Do you know what pH is? How long has the plant been in veg state? Do you have pics?
