Cal-Mag with organic soil?
generosityjoestarted grow question 4y ago
Hello everyone!
When using organic soil amendments, does everyone still use Cal-Mag? And if so, at what age of the plant do you start, and how often?
Thanks

You should not need to use it, but it is a good supplement to have. Every plant is different.
