Organic fertilizers do not work well in so called soil-less mixes because they require the action of soil microbes, which such mixes lack.

wrong n-p-k ratios

What n-p-k ratio am I looking for? And is it good for all citrus?

i think in general, most citrus likes a 5-1-3 ratio. What kind of citrus are you growing?

Well, I'm just a "newbie". I've got a baby lemon tree, a couple seeds trying to be grapefruit, and a kumquat seedling.

5-1-3 for all of them. For seedling after the root is 1.5 inches long I lift the plant a half inch so the green stem doesn't get damp off. every Neiwa seedling has at least a half inch of root above the soil line.

Steve, those little trees look so nice a green. Good job. You know me, it's all about the color!
