Debbie from Duncan, Ok writes

If I’m just watering a few plants and I use gallon jugs with Peters Excel 15-5-15 Cal-Mag Special Fertilizer, how much?

How much do I put in a gallon to just pour on the ground? I just grow a few cannabis plants in the ground. And I need to know how much of this goes into one gallon of water.

Answer:

Peters Excel 15-5-15 Cal-Mag Special Fertilizer is not for use on anything edible/smokeable, only for use on Potted, Bedding and Cut Flowers. Unfortunately, we are unable to provide advice on cannabis treatments.
