When to use Epsom Salt with Hempy Buckets?

Do you use it as a preventative measure?

Only when a Mg deficiency is present?

Not at all in a hempy set up?

I'm doing some reading and need some clarification here.

Thanks!!

You got yellow leaves but the viens are still green thats (Mg) def. use cal mag or better Epsom salts, to my blog: https://www.rollitup.org/blogs/blog32270-magnesium-deficiency-mg-def.html also here:

Never used Epsom salts, but I did use calmag as a preventative measure for a while. Had a go without it and everything was fine so I stopped. That is generally how I approach things these days. If everything is fine I just leave it alone.
