How to Use — Powder Fishtelizer®

For use on top of soil, spread powder evenly over the surface — at least 0.7 lbs per 100 square feet, depending on soil need.
For mixing in water: 10 grams of powder per 1 gallon of water. For spraying/watering, mix 1 oz (29 grams) per gallon — a ratio of 126:1.
When adding to soil, blend the powder into growing soil for even distribution.
Use growing soil soon after adding the powder.
Water should be applied soon after the powder is applied (adjust amounts to the plant's cycle, type, and environment).
Store in a cool, clean, dry place.

Recommended rates are a guideline and may not suit all environments. Use care when handling any fertilizer and follow all instructions. It is the responsibility of the grower to determine the correct amount of ingredients.

I never received my product.

I've been using this for about a week on my veggies. It's having a good effect on everything, especially the lettuce. No bad fish smell either.
