Greetings Shelia! For raising seeds, we strongly recommend an all purpose water soluble fertilizer as it’ll be immediately available to the plants. If there is a seedling dose specified, use that. But, if not, the typical seedling dose is about 1/8 to 1/4 of a normal dose depending on whether the seedlings are very young (1/8) or a little more established (1/4). The brand of fertilizer doesn’t matter a lot. It can be non-organic or organic, but the most important thing is water soluble. Hope that helps! We should have this info in at least one of our from seed articles, so I’ll also hunt for a good place to put it.
