Liquid/Aquaponic Fertilizers

I'm gathering up all the supplies I need to grow some leafy greens and herbs in my super small-scale aquaponics-in-a-jar setup.

Does anyone here have experience with liquid fertilizers/nutrients? I'm wondering what brands may be best to start out with? Especially with limited space and keeping weight in mind, I'd love to find a powdered mix that I could then mix up in water as needed.

Does anyone know of a "feeding chart" sort of guide for what types of plants need what sort of nutrients when grown soil-less? I have been looking them all up individually but figured it was worth asking if anyone knows of a sort of repository for that info too.

    Aerogarden makes liquid fertilizer suitable for indoor aquaponics, but it is not organic.

    I use Superthrive liquid for outdoor plants; it is organic, based on fish so smells badly.

    @shllnzl Thank you for this - The Superthrive looks promising, though I'm not sure that it covers the full spectrum of what they'll need, it may be a great option for adding micronutrients. I'll do some more reading into it, thanks again!

    I should have mentioned above, but I definitely want to keep it organic as I'll be hoping to consume most of what I grow with it.

    @Linzi You're welcome. Fish fertilizer usually has low numbers so you can get it on the leaves without burning them.
