Don't Know the ratios and not a pro but if it wher me:
Blood Meal: Carful or not at all for tea, only when plant it established (Tea? mabey 1/8 teaspoon per gallon to start?)
Bone: not much good for teas but dosent hurt
Kelp: as much as 1/4 cup per gallon (this might be a bit much but it's alot safer than blood) BUY SOIL FUNGUS AND BACTIERIA: SOIL MYCILIN, THE BEST THING FOR YOUR SOIL AND FERT. TEA
