I'm not seeing what you call washed out, but several of those are showing Mg deficiency. Are you using RO water? If so,ya need some Cal-Mag+. You should really give more info when u have a prob. Like what is the environment like, how often you water, what nutes you use and how often you use them, what kind of water, pH of water, pH of runoff, what kind of light and how close, etc. But, Mg would be my guess from the info provided.
