Well, she needs help - but then so do we... your diary is incomplete in that you're not telling us anything about the nutes you're feeding her at this point - nor about the pH level you're maintaining for her. Most all deficiencies start because the pH is not being held within a specific range... growing in soil, you want this to be between 6.0 and 6.5 for the plant to be able to absorb all the nutrition you're supplying her. If that is not a problem, then perhaps it has been caused by giving her too much nitrogen which can also cause a lockout. The very last reason you've got this problem is perhaps because you're not feeding her at all or haven't introduced bloom nutes and cut back on grow nutes... But that's all I can tell you at this point. If you can update your diary with nute and pH information, someone will have a better shot at helping you. -
Good luck.
p.s... the questions page is not like chat so even if you tag someone in a message here, they're not going to be notified... If you don't get more answers, fill in your diary and ask the question again... at the bottom of the diary page itself, there's an easy access to pose your question and it links your question to the diary so we can quickly find what we need..
