is this organic mix good?

Wood ashes (2-3 cups per hole)
Coffee grounds (1cup??? per hole?)
bone meal (1cup or a lil less per 3by3 hole)

I dont rly know the amounts of each that I should use to last threw veg stage per plant any advice would be great

if its all organic they cant burn my plants rite? so I was thinking just doing like 3-4 cups of each to be generous other then the bonemeal cuz its $$

Also where can I get items for my soil like dolomite lime wtf lol and trace minerals epsomsalt and how important are they for plant growth

basicly im looking for a dirt cheap organic fert mix with everything a plant needs

Sound Good
