I wouldn't be too concerned about the humidity at this point. It looks like you have some nute burn. What nutes are you using and how often? Could also be causing some nute lockout too. I would flush them well, let them dry out for a couple of days and start back with nutes at 1/3 or 1/4 strength. Try adding a teaspoon of epsom salts in a gallon of water once your flush is done, when its time to start back with nutes. Should see some improvement in a week or so.
