I had an organic vegetable garden for years. I would put a whole egg in the hole I dug at planting for the tomato plants and that usually was sufficient for the season, provided I had plenty of organic compost mulch tilled into the soil. I don't recall the other concoctions I used.

I got lazy and returned to miracle grow a few years back. Good luck

Sounds interesting.

How are you testing the fertilizers?

Just use and see if the plants will show or won't show signs of missing nutrition after some time?
