I'm pretty sure I have a zinc def and can't seem to find any info about how much chelated zinc I should use per liter/gallon. Anyone have any good advice on this?

As a rule of thumb for perfect soil balance, Zinc should have a min. of 7ppm up to 50ppm, or 1/10th X P (up to 50ppm)
1ppm = 2 grams per 100 ft. sq. or 2 grams per 10 m sq.
ADVICE: get a soil sample test that registers zinc. and add the difference...also, copper (cu) needs to be 1/2 of zinc to work effectively...
use distilled or RO water with a 0ppm then add accordingly... You should only be adding minute amounts, kelp or kelp meal is a good source for both elements and many others...
