Greenway Biotech Cucumber Fertilizer 8-16-36 vs Drip Hydro 5 lb Micronutrient Fertilizer

Buy the Greenway 8-16-36 if you want one powder that feeds cucumbers through the fruiting stage, with potassium and phosphorus already in the bag. Buy Drip Hydro Powder D if you already run a base nutrient and only need the micronutrients, especially in late flower when extra nitrogen hurts. The Greenway is a complete NPK plus minors; Powder D is minors only, so it is not a standalone feed. Greenway's 3.6 rating from 14 ratings is thin, and the label itself warns it lacks calcium and magnesium.

• Choose the Greenway 8-16-36 if you want a single water-soluble powder that supplies phosphorus and heavy potassium for cucumbers, squash and melons, and you are willing to add calcium and magnesium separately.
• Choose the Drip Hydro Powder D if you already have a base nutrient and want chelated iron, manganese, zinc, copper, boron and molybdenum without any added nitrogen.
