Ideal fertilizer

Dear Ed,
We have tried different variations of N-P-K ratios in nutrient solutions. Is there an ideal N-P-K ratio for vegging and flowering?

Greengenes,

There is no universally ideal fertilizer for several reasons. First, the quality of water varies and fertilizer requirements vary with the mineral content of the water. Second, different varieties of marijuana have different fertilizer requirements. Third, nutritional needs change with environmental changes. Light and temperature conditions have a tremendous effect on plant needs. Fourth, marijuana’s nutritional needs change. Early and late vegetative, early, mid and late flowering each have unique nutritional needs.
