I too am unaware of the specific fertilizing effect of apple cider. I believe the greatest advantage of molasses is to stimulate the microherd.
I you are mixing fertilizer in you soil mix, I'm not sure that your supplemental liguid would even be necessary at seeding time.
There's a possibility that your list of granular ingredients may be to "green" for a pot and its decomposition could be a problem.
Interesting to hear what others say. :)

What kind of potting medium are you using? It won't matter what kind of fertilizer you use unless the potting mix is a well functioning one.

You might want to research the value - or lack thereof - of utilizing any sort of granular organic fertilizer in a container gardening situation. High quality potting soils tend to be essentially soil-less and therefore the soil biology needed to mineralize and assimilate/digest these types of fertilizers is missing or substantially lacking. Most liquid or water soluble organic ferts won't do much better -- they simply lack a full range of both macro and micro nutrients, minerals and trace elements.

And I'd also consider doing some research on the pros/cons of foliar feeding. Plants will absorb some of their nutrient demand via the foliage but the vast majority will need to be processed through the root system as nature intended.

I know a lot of folks don't like to hear it but it is hard to be 100% organic as well as 100% successful in a container gardening situation.

If you read up over on the container gardening forum you'll find there is a relatively foolproof container method using mostly pine bark (known as Al's 5:1:1 mix) and a ~1/4 strength solution of fertilizer given with each watering, although this wouldn't be considered organic.

Emgardener has done some interesting trials using "Zero Cost Organics" in containers. If you search for emgardener gardenweb you'll find more.

There are many ways to achieve success with your plan, but it may take some time to figure out what works best for you. You might consider growing in the ground or building raised garden beds.

thank you all for your replies.

sub-irrigated container gardening is my best bet in the extremely hot and drought-prone climate in which i live. we also have dreadful soil conditions--a thick, impermeable layer of caliche underlies our thin, predominantly clay, alkaline topsoil. in addition, i have physical limitations that largely preclude in-ground gardening as a viable possibility for me (i have a bad back).

regarding my potting mix composition and the necessary soil biology appropriate for granular fertilizer, i am doing a 2-2-1 mix of pine bark fines, sphagnum peat, and coarse perlite. i do believe it to have a suitable balance of wicking ability, drainage ability, and aeration for my purposes and in my climate. the granular fertilizer, espoma garden-tone, includes application instructions for containers on the packaging, so i probably wouldn't be the first person to use it in a container. as it relates to mineralization/"digestion", the fertilizer does contain "895 colony forming units" from a variety of microbe species. i do not know to what extent this promotes nutrient release/'digestion', but it certainly can't hurt. finally, i am inoculating my seeds with both endo- and ecto-mycorrhizal fungi prior to planting, which is good for soil chemistry and increases nutrient absorption by a symbiotic relationship.

i think that is the most i can do to encourage a healthy growing environment without introducing compost or other dense organic matter that will weigh down the mix significantly and hold way too much water.
