home made fertilizer made with shredded plants and nutrient enriched water

blend and then let compost with some soil. does anyone know if vegetable compost will provide all or most of the nutrients i need?

u would do good but make sure u make compost tea

Vegetable compost can help give many things to your soil. Vitamins, minerals, and such, the levels will be determined by where the veg was grown(what was the soil like? Rich in nutes, or did the grower add?), as wells type of veg you are composting. Adding soil will help to increase breakdown, IF it's not a sterile soilless mix. You can add beneficial microbes and fungals that will further increase availability of natural nutrition to plants when the compost is done.

Iactually add all household food scraps with the exception of citrus, brassicas, and greasy/oily stuff. You can add eggshells, newspaper,etc. These things will help give more food source/energy to the bacterias and enzymes that are doing the work in the compost.
