Help. Brown spots out of no where. 3rd week of flower. In living soil

[J1XD]

Hello, to my knowledge I was taking great care of my plants. Out of the blue over night there's brown spots on the leaves near the bud sites.. the only thing I can think I did different is usually I give a half a gallon of watering every 3-4 days. But the last watering I gave it a full gallon of water. It's been 2 days since I watered them. I don't know what's wrong

And it's just this one plant. The other 2 are fine

I also have a living soul grow with a similar problem on two plants. I’m about to switch to flower. I’m curious to see who chimes in.

Did you use “Earth Dust” by any chance?

@Shaded_One Do you think it's a calcium/magnesium issue?

 

[smokedareefer]

Calcium

Calcium

So how does living soil work . How/when do you feed it?

@Shaded_One Do you think it's a calcium/magnesium issue?

Rust spots (circular) are typically calcium but def looks to also be an magnesium issue also. Improper watering can and will present itself as similar issues.

Cuople tablespoons of some Epsom and some Gypsum prob wouldn't hurt on the next watering (or whatever you use for nutrients I don't think you mentioned)

I don't use any nutes on thos plant. Plain old ph balanced water. It's living soil so I thought I could not use nutes. Can I just use Cali mag?

Get some down to earth gypsum and some equate epsom salt (unscented) . What size of pots you using? I can give you the dose. I use 2 Tablespoons of each of them for a 7 gallon. Got to use organic amendments to keep your living soil alive.

I think their cal/mag is their cal/mag. That's a 2-1-2 fertilizer with microbes.

Really looks like Cal def.
Adding MG usually does not hurt.
I don't grow organic, I like to have control over the ferts I need when needed.

I try not to nutrient-steer people but you know I lean heavy organics, he just needs to find a method to get some micronutrient coverage :)

What's the difference from the stuff in the link u posted vs this...

 

[2Bad]

I say go with the cheaper, clearly labeled stuff. If u got 3gallon pots then it’s 1tbs every 2 weeks of each of them. And sorry to hear that garbage I thin some of the grow stores are just idiots tryna cash in, I got one of those guys that I go to lmao.
And if neither of them say Omri then they aren’t organic certified.

 

[2Bad]

There’s also nitrogen in the one you just shared @J1XD which you don’t want

 

[2Bad]

I’ll be honest roots organic is probably organic because it is cdfa certified which I just learned about on Google lmao.
