Advice for using cal mag

CrypticBMB
CrypticBMBstarted grow question 4 hours ago
I’m about to start my second grow, my media is 70% coco perlite mix 30% worm castings and i’m using gaia greens dry amendments, I’ve been told I should also add some cal mag. Should i add the cal mag to the media or wait and top dress. At what point would you add the cal mag?

Hey grüß dich. Bei anbau auf cocos kann etwas calmag nicht schaden. Ich benutze GreenHouseFeeding, das ist ähnlich in der Anwendung wie Gaia Green. Wenn ich das Substrat fertig mache, mische ich zusätzlich 2g/L Substrat Urgesteinsmehl mit hinein. Das liefert neben calmag auch andere Micronährstoffe.

Look up buffering coco. You can pre soak coco in the cal mag solution to basically charge it with calcium and magnesium. This is done before mixing. Coco will pull magnesium and calcium from media and is why you have to add cal mag when using it. If you pre charge it with cal mag, you can extend time before needing to add it. There's a couple good videos out there explaining this and how to do it. Best of luck! Happy Growing!

Just go small and see how she acts from that I use canna calmag and in coco I would give ½mll every other feed until bigger then up to 1mll every other. Bit your plant will dictate.. it's only because the coco will take small amounts magnesium so really your just topping that up so some gets to the plant.. Don't go mad with it.. small amounts..
