I only did preliminary research and realized it would be to much hassle. You would use the same fish. You wouldn't change chemistry for flower. Also aquaponics is better for lower feeding plants, lettuce and greens. I read this is one of the better books on the subject https://www.amazon.com/dp/086571701X/ref=cm_sw_r_cp_apa_fabc_FcDaGbB0X7NQT?_encoding=UTF8&psc=1
Aloha, and welcome! I would start with either Bernstein's book Aquaponic Gardening and/or Small-scale Aquaponic Food Production (free option). You will get a better start from either of these resources.
Bernstein's book was my first one.
Some of the information/rules of thumb are a bit iffy, from what I'm told, but it's a good start, and you'll have edible plants.
This book was recommended by a friend when I first got started.

Very experimental for me, but I'm largely following Sylvia Bernstein's guide
you made the claim not me, so you do the heavy lifting. saying that, you could start by reading:
http://www.amazon.com/Aquaponic-Gardening-Step-By-Step-Vegetables-Together/dp/086571701X
then dig deeper:

you seem confused or don't know what you're talking about. aquaponics = aquaculture. the terms are synonymous. if someone is using aquaponics, by definition they are raising some sort of animals (fish, snails, crawfish, et c) to bump the nitrogen count.
>The ideal nutrient density in a hydroponic system is a lot higher than what fish can tolerate.
you lost me.
if you take the time to review some of these sources, you'll notice that they cite sq footage that is even lower (25-35 sq ft) than my number. my numbers vary because some of the crop i grow doesn't lend itself to high density. saying that, i'm going to transitioning several of my inline grow beds to 4-5ft high towers so i get some gains there. http://www.raederle.com/2012/11/land-feed-person-overpopulation-green.html#.VOU5JfnF_Qo http://www.aquaponicshowto.com/how-much-space-is-required-for-an-aquaponics-system/page/60/ http://theaquaponicsource.com/2012/07/09/aquaponics-and-setting-unrealistic-expectations-about-vegetable-production/ http://portablefarms.com/2015/feed-8-people-forever-portable-farm/ (scroll down to the faq's) http://thesurvivalmom.com/an-aquaponic-system-can-provide-a-healthy-food-source-forever/ there are several reference books regarding topic, this is the one i have and it reports similar results: http://www.amazon.com/Aquaponic-Gardening-Step-By-Step-Vegetables-Together/dp/086571701X if you really want to dig deeper i remember a university of hawaii study that really explored nutritional density. i do use led lights to gain a couple of extra growing hours each day, the electricity cost is negligible. the irrigation system i use has two pumps and the rest is done with gravity.
here's my reply to another post:

personally i'm more interested in the automation side of the community, the goal is to establish a food appliance that uses the equivalent floor space of a couch that can feed an adult male year round with minimal interaction and input:

i also highly recommend "the resilient gardener" by carol deppe.
I read Aquaponic Gardening by Sylvia Bernstein (https://www.amazon.com/Aquaponic-Gardening-Step-Step-Vegetables/dp/086571701X) before starting a small hobby system. It's not geared towards the science or business side but I thought it was good. It does have info on sizing, building, choosing fish, cycling and maintaining a system. You can find all that and more in the links people shared but the book is a good coherent baseline to start a small system.
Aquaponic Gardening: A Step-By-Step Guide to Raising Vegetables and Fish Together is currently my go-to source for good info. HIGHLY suggest it!
Also, Citizen Peng's videos are a must watch!
