What are my peppers lacking?

Do you do this as an every day maintenance on plants or only when they're starting to show malnourishment?

I try to spray a few times a week. Whenever I get a chance or 'remember'...

Nice reference website.

If I did what those guys are doing, I'd never 'remember' to spray... ...
They are pretty serious about their plants. Seems like they have some great info. I also have a great pdf about bat guanos, I saved from their site.
