I grew several varieties and only the San Marzano and Roma tomatoes were presenting blossom end rot (BER). I used this once per week for 2 weeks and it all new fruit did not have BER. My new garden staple.MemphisDiva
I'm growing 2 strains that are extremely sensitive to nitrogen excess and needed to supplement with some CalMag. This was the only product I could find that didn't have any nitrogen.Mike T
Very strong, organic Cal Mag product. Very low usage. Don't overdo! A great company with great products at great prices. Try their great, organic Silica Gold product. Best I've used!Tim T
I realize people use this for hydroponics, but this stuff is great in the garden. It's complimentary to other organic fertilizers. A tiny amount is more than enough.Mamamater
I absolutely love this cal-mag product. I use coco and RO water and while I supplement with this product I have never had a cal-mag deficiency. Or any deficiency for that matter with the TPS Nutrient line.Daniel
I use this as a foliar spray and my plants love it. My favorite brand for my peppers that need nutrients from time to time.Brennan K
