## Questions & Answers

**Q: Can you use this for Hoyas or are the numbers too high?**
A: People saying the numbers are too high don't quite know what they're talking about.  It doesn't matter if it's a 20-20-20, 2-2-2, or 80-80-80 as they all have a ratio of 1-1-1.  The only difference is how concentrated each one is and how much of each you use. With a higher 20-20-20 you'd use much less than a 2-2-2. In the end, it's all the same as the ratio is really what's important.

**Q: Does it have magnesium?**
A: 0.05% Chelated Magnesium

**Q: Where are the ingredients derived from, and is it ok to use in an organic garden?**
A: Not 100% sure what its derived from, you would have to call the manufacturer. And this is a "synthetic" chemical fertilizer so it may hurt the organic material thats already in the soil. If your after yield, this fertilizer will blow away any organic fert on the market. If you give your garden a 1-2 week water only diet near the end, your product will not taste anything like chemicals. I have been using it for over decade, and wouldnt use anything else. Its the BEST!!  Good luck :)

**Q: Can I use this fertilizer On a small rooted cutting? Or will it burn its roots ?**
A: Yes. I use this on my newly rooted cutting after potting them up. Make sure that you dilute it. 1/8 to 1/4 teaspoon per gallon of water.
