I don't feed my plants in flower.

We are waiting for an understanding.
Organic living soil is my guess.

Haven’t used Calmag in years.
If you’re using salts buy one that has Ca and Mg in it already.
If you’re using soil, there are plenty of amendments.

mix up, loads of cheap dry plant food, sand, and perlite in my reused soil 60%(from my last crop) and add 40% new cheap compost from my local garden center), mix it up and pot up a week before flower.
Flowering them off in 29ltr pots, veg them in 7.5ltr pots

Epsom salt is the Mag in Cal Mag, dude.

Its a good source of Mg but its not the Mag part of CalMag

Maybe for other brands, but Epsom is not an ingredient in GH Calmagic
It uses Magnesium Nitrate for the Mg

In each 29ltr pot there is:
sulphate of potash 2tsp
seaweed meal 2tbsp
chicken manure 3tbsp
fish blood and bone 2tbsp
Bonemeal 2tbsp

about 3ltrs of perlite and 2ltrs of sharp sand.

In promix with extra perlite, i have fed gh nutes with tapwater, and no calmag. It didnt seem to be a problem

I second this. Only I’m using canna coco and tap water. I’ve never bought cal mag…ever

So he IS feeding in flower. He’s confused :hump:

I believe it can be done but
I don’t see how a repot a week before flipping can build a root base with that hot of soil ?

i think technically he is correct but it's 100% click bait.

your right.
but A strong healthy plant with a well-established root mass in a 7.5ltr pot can handle the hot soil mix.
The same soil mix could kill my plants in early veg.

The roots keep growing in flower, slow down 3-4 weeks in flower

I’m aware but I just feel they stretch and search for food and hitting that mix it seems they wouldn’t
But hey I have no direct experience in trying it

Calcium Nitrate plus Epsom is also Cal Mag. The point is you said you weren't using CalMag, but you are using half of it.

PeatPhreak · Dec 30, 2021

I don't add CalMag or Epsom to my normal feed.

Just Jacks 5/12/26 and Calcium nitrate. The blend contains more than enough Ca and Mg.
