I want to use solutions of Gypsum and Epsom Salts to augment the nutrients in my pot plants. They seem to be having some mineral deficiencies. I'm wondering what is the correct amount of Calcium Sulphate and Magnesium Sulphate for a two-liter solution.
I would also like to ask whether it be better to spray my plants bi-weekly or once a week.
Although these are not my plants the problem is white veins on my squash plants, which is because of a Calcium deficiency in the soil (As I was told.) (This may be bad advice, I'm still new at this.)
