- Ideal basic feed for most low light situations
- Multiple forms of iron chelation to work over a broad pH range

Developed as an alternative to Cal Mag 17-5-17+ to give greater control over vegetative growth without sacrificing the calcium and magnesium. It has a neutral potential acidity, and it also contains a combination of three different forms of iron chelates, EDTA, DTPA and EdDHA that makes iron available over a broader pH range, as well as in wet soil conditions. It will ensure availability under alkaline soil conditions.
