Organic Plant Food For Indoor Edible Garden

Hi:  I have another post in this section about having problems w/ indoor container garden.  It was advised there that I would need a good liquid fertilizer. I agree. I started this new thread as it deals with that topic alone.  I do not have a lot of funds and the fertilizer needs to be organic.  I have used fish fertilizer in the past, but can not use it here, as I have a huge sewer fly and flying bug problem, in the house and find that using fish fertilizer makes my home unliveable.  I have heard about seaweed fertilizer like this one: amazon seaweed fertilizer, but boy is it pricey.

This other one looks great, but at this time no way can I spend $50 to get the shipping removed or pay tacked on shipping, so it is too costly to be doable, but looks like a great product otherwise:  fulfilled only by amazon fertilizer

I was reading things online about making your own cheap:  using urine would be great, but it's out for me, as I have high mercury levels and other toxic levels and do not want to add that back into my food.    

I do have some sea veggies that I will probably soak a serving of maybe in a week, when I finely have a day where I will be eating and can save the water from that, and use that.  It seems that may be close to seaweed fertilizer. May be my best bet till I can manage to purchase one of the pricey ones on amazon.

I have heard about using left over tea and brewing a second time and pouring the water over. I am not consistent w/ my tea and use herbal that may be meadow-sweet or echanancia or white willow or "throat coat".. I sometimes dry out the tea and save it to mix into soil. I do not drink the standard black tea I thing most refer to using.

So could use some guidance and ideas here.
Thanks

I have had the same issue, but think I figured it out now. What to use inside? Left over coffee isn't strong enough. Fish emulsion stinks. Organic stuff for out doors creates fly problems. Same with improperly made compost. I read online people using worm castings soaked in water as a tea, and some other blends. Last year I used fish emulsion in low quantities to help with the smell; like a little plop in the watering can that would last like a week, and that helped with the smell and I got no flies out of it. For fly issues I also found my compost bin worked really well as a trap. They would go lay their eggs, then I'd go soak them to death and clean it out. The horrendous fly problem we had due to some bad plant fertilizer choice disappeared in about a week and had never been back. I also keep a little plant deficiency chart handy and add other things as necessary, like Epsom salt or Tums, etc.
Good luck!

I recently found this resource, it is what I would like to attempt.  One thing I am finding... organic is sure pricey.

Worm castings, as an example, are simple to make at home even in an apartment. All you really need is an out of the way corner to store a bin. In a cabinet is fine. Saving eggshells isn't hard. Neither is asking local coffee shops for used grounds.
Experience helps you learn cheap alternatives where necessary and identify when something is just a nice bell or whistle but ultimately not essential. At it's barest essentials you need soil, organic matter, water and light.

My family has always gardened organically and we got started precisely because we didn't have money. My young, widowed mother needed to feed us and couldn't afford the chemicals everyone else was using. We went without air conditioning, hot water in the summers, and salt for our beans, but; she kept our bellies full of nutritious foods. If it was expensive she wouldn't have been able to do it.
