As for your fertilizer, the middle number should be higher during blooming (at least I think that's what I read), but you should be diluting it to a weak solution and feed weekly (or, weakly, weekly). I'm using a balanced formula Miracle Grow, and I think I used it 1/4 strength.
There is no magic wand unfortunately. I have spent days on end here, reading everything I can (who needs to clean??). I will be joining one or two local societies in the next two weeks, and mostly, I talk to my new babies every day. Talking to them makes me take a good close look at them, and that way I can hopefully stop any problems before they get started. Worst case (or best), the AOS is just about a 1/2 hour drive from here, and they have an orchid doctor on site once or twice a week to offer help and advice for problems.
Basically, after reading and reading here on site, I think it's a matter of trial and error. What works for one, sometimes isn't the best solution for another.
