Equal parts of 5-1-1 and 0-10-10 (Alaska Fish and Alaska
Morbloom, great stuff) would yield what NPK figure?


These are weight percentages so you just take the average for 50/50
blend or proportion for any other blend.


So I thought.

Indeed, the numbers represent percentages by weight. If you mix equal
weights of these two, you will get 2.5-5.5-5.5.


Close to the standard all-purpose 5-10-10 ratio, ideal 1/2 strength.
