Cal mag for autos

[Ayokiwi717]

So my one auto looks like he's having magnesium problems. So I just ordered cal mag, so how do you use this with autos? I know autos are sensitive, so how much should I put in a gallon of water?

Should say on the bottle. I typically use 1 tsp per gallon of water. What type of water are you using? And it doesn’t matter whether you’re growing autos or photos to use calmag.

Are you positive? I know for nutrients it needs to be 1/4-1/2 the dose. Is it safe to mix in the that dose with my nute water that I give to the rest of the girls, or do I only give cal mag to the one that has the deficiency? I will have to take pics then. My other three have some nutrient issues, but not nearly as bad. Like I said will have to show pics of all of them.

Are you growing in coco? If so I understand the dosing. If not, I’m not entirely sure why you use the strength you do. Some Nutes are hot like Fox Farms Trio for example, I myself use half strength, but it has nothing to do with it being an auto or photo. And I don’t mix my mag with my nutrients, I use mag on my water only days.

I give full dose of cal-mag with 1/4 strength nutes for autos. I have very soft water and found lowering the CM dose caused deficiency.

Watch out for any extras in the CM though. Some brands contain N which will mess up your dosing if you don't account for it.

Treating magnesium def is use Epsom salts. Calmag has higher quantities of cal to mag which can antagonise magnesium.

also before u do any of these things make sure your pH is in check.
