IF you want an expert opinion of a plant problem, I'll caution you now, you will want to put this in the troubleshooting forum and fill out the form: Look in Dutch Pimps Signature and Bigsby's..I think, all the information you need, before you post, maybe found, there.

Your question is: You have one White Widow, you've had it in veg 2 weeks..and listed your soil, etc.
