## Questions & Answers

**Q: Is there a kit available that contains the master blend, and also the  calcium nitrate and magnesium sulfate .  sure would be nice .**
A: Yes, sold in amazon and work great. Instructions on the bag and good price.

**Q: What the best way to adjust EC if its to low and you already mixed all 3 parts together**
A: First, you should not mix the calcium nitrate together with the master blend and magnesium sulfate (EPSON salts)  at the same time. Mix the master blend and EPSON salts together and mix the calcium nitrate separately before adding to your nutrient solution. When you mix all 3 together at the same time it binds up the nutrients and they can’t release properly.   See if mixing them separately before adding helps.

**Q: Can this fertilizer be applied directly to container plants or must it only be used in a hydroponic system?**
A: Container plants will love this. I top dress soil and water in. I also measure it in filtered water to apply. It's very good stuff.

**Q: Newby here, I have an organic container garden, are this supplements synthetic? I purchased this and not sure if I should use it.**
A: Totally synthetic, so now what?

### ⭐⭐⭐⭐⭐ Keeps vegetables green and healthy
*by E***. on September 13, 2025*

Awesome value for money! The light green powder mixes well and easy to use. It lasted me over a year and its super effective for lush and hefty vegetables!

### ⭐⭐⭐⭐⭐ Excellent nutrients for Kratky method hydroponics
*by L***. on July 14, 2025*

I use this blend with my small scale Kratky hydroponics system. It's very effective at supporting plant growth. Easy to mix in a five gallon bucket, it lasts a long time. I grow mostly lettuces and tiny tomatoes and this nutrient solution under a grow light and this assures we have fresh salads all winter long in Ohio. I've noticed a lot of Kratky method growers use this brand, and I can see why.
