You can give us more info. We can't help you if we don't know all the variables in play.

Don't immediately assume you're facing a deficiency. Much more common and possible answers would be over-feeding or insect action.
We can't answer any of your issues without more info. Have you been feeding them... what kinds of lighting.... what kind of grow.... etc.

Do you have a PH meter? Run Good Ph water through the plant and test the runoff. Your problem sounds like it could be a lockout due to high PH. But ofcourse we could get a better idea with a pic.
