I don't know how familiar you guys are with First Ray's website, but he has a ton of great info there. Here's his take on fertilizers and there's a calculator at the end of the article for those that are math challenged like me.

I pretty much fert at 125PPM every other watering. Masdies get about 50PPM every other watering, other wise they tend to suffer from too much. I use collected rain water.
