## Questions & Answers

**Q: How much will this make?**
A: Mixed at 3ml per gallon it will make 320 gallons.
Mixed at 5ml per gallon it will make 192 gallons.

**Q: Is this carbonate based?**
A: Near neutral pH, ferric ions form insoluble solids and are thus not bioavailable. EDTA (and other chelating agents) address this problem, by forming soluble complexes that resist formation of hydroxides. EDTA increases the bioavailability and plant uptake of the metals in the soil

**Q: How long can this be kept and or stored**
A: Product warranty on nutrients and supplements is 1 year past the date of manufacture. Stable shelf life can run past this substantially if unopened, but this time greatly depends on storage conditions. Once a product is opened, it should be used within 6 months, or ideally- the time it takes to cycle a production garden which is typically 12 weeks on average. Opened products may last longer than this, but it should not be expected to be the case.

**Q: Can this be used for Tomatoes, Blossom end rot?**
A: Yes, this works well with Tomatoes.
