you dilute all fertilizers with water, yup ... if you have a garden shop near you, try the Fox Farms' line of ferts, just follow their ratios, and schedule ... they furnish a little brochure with the details, or it's also on their website ... if not available, you may use something like Miracle-Grow, or Schultz ferts ... if you use these, DILUTE THEM TO 1/2 STRENGTH,and only apply once weekly ... absolutely nothing wrong with these ferts, only that people over-apply them ... good luck :thumbsup:
