Nutrients 5-12-26 Part A Water-Soluble Fertilizer for Growth of Leaves and Strong Roots in Plants Grown in Continuous Liquid Feed Programs, 2.2Lbs

Great nutes. Been running the 321 system for years. Simple and great results

High quality nutrients

This review covers the Jack's 3-2-1 ingredients: Part A (this item), Part B, and epsom salt. It's easy to mix and use, it costs mere pennies per feed, and it can be used from start to finish for growing cannabis without anything else. Simple, economical, effective.

I use the Jacks 321 formula with fantastic results. Won't burn plants and super easy to use.

Great product needs to be shipped better about 20 grams was in the box and the bag was ripped.

As expected

Works easy. 1 feed for all my tents no matter the stage or age and no matter veg or flower. 321 start to finish. I have ran multiple grows with this by now. No need for cal mag or anything. Also all the epsom salt is great for turps at the end of flower and 321 is loaded with calcium and Mag. P.S. Make sure to buy these white bags, this is new nutes for cannabis. The blue bags that say jacks professional are for regular agriculture. The white bags ( jacks nutrients) along with bloom booster are special for cannabis. It all have more micros for cannibus. I spoke with a rep.

Delivery was actually one day early. These nutrients are consistently good and I wouldn’t use any other product in my hydroponic system.
