It looks like something might be locked out. I'm not the greatest at diagnosing issues other than my own, but I can tell you that others who are will want to know what the pH of your water AND soil are. This is very important to know. Also, listing what you've been using to fertilize, as well as the frequency of application, might be a good idea. Also, what's your water source? Tap, or distilled/RO/bottled water? Take a look at the troubleshooting form at the top of the 'Problems' section, and fill out as much as you possibly can.

Sorry I can't be of more help, but by figuring out some of the variables I listed above, you should be able to get some more accurate advice. Take care!
