  5. If you can hit the link on my signature. You can post it there. Btw a lot of def help as well as links to pages that'll help also.
  6. you dont have any type of deficiency that can be cured with fertilizer. in fact, you have way too much of stuff.
    the burning on the leaf margins tell me they have too many nutrients, resulting in a salt toxicity. the extremley skinny green fan leaves also seem like excessive nitrogen.

    flush your soil out immidiatley. you are experiencing a phosphorus deficiency because your soil is tied up with other salts. before adding more salt to your medium (phosphorus) (every nutrient/fertilizer is a salt), you should make sure your root zone is free of these toxicities. thus, a flush is imminent. if you like, you can use a small dose of H202 (20mL per gal of grocery store purchased peroxide), which helps leech out the salt quicker.
