Your best bet is to start a thread in the Plant Problems section and fill-out the appropriate troubleshooting form as best as you can. (the link to the form is in my signature) The more questions you can answer, the better your chances of an accurate diagnosis.

While you are waiting for someone to help, you might want to read through some grow logs and see what it takes to take a crop to harvest. :thumbsup:
