The hydro-gardens nutrients are usually sold to greenhouses for commercial crops from strawberries and cucumbers to lettuce and tomatoes, with custom blended formulas for each. They even have formulas that compensate for hot climates.
Since they're in Colorado they do have a '4-20' formula specifically blended for cannabis- but the important thing to remember is that the base nutrient salts are all the same.
I'm very happy with their 5-11-26 hydroponic special formula. Add a bit of MKP in bloom and some mag sulfate and it's all good!
