Not sure what this is.

This from my outdoor sips. I grew tomatoes in them. Organic soil topdress with Gaia and ewc. Not sure if it’s mould or what. It’s granular in texture and it was in clumps before I broke it up.
What say you?

 

[myke]

Looking at its location. I think this maybe what’s left over from my Gaia top dressing?im finding clumps of it exactly where I made trenches of Gaia.

Looks like battery acid.

Ha. I’m sticking with fermented Gaia fertilizer.Can’t find info about it so gave up. Can’t really be anything else.

Do you water aggressively on top by chance? Fert companies sometimes put anti caking agents in and if we water aggressively we can get stuff to separate out like that.
Most anticaking agents are made from synthetic substances such as silicon dioxide, magnesium carbonate and iron ammonium citrate. Calcium silicate, commonly added to table salt, absorbs both oil and water. Natural anticaking agents include magnesium silicate and corn starch.
Just a total guess though

I think your maybe on to something,these are sips so very little top watering.But when you water over the Gaia it beads and just runs off.Exactly what anti caking agents are made to do.With my other fertilizer like Kelp,Alfalfa etc water absorbs instantly.

I only start to care when a foriegn substance is red or blackish. Ur fine man.

Calcium build up from hard water.

I dont think thats strictly from hard water source mate. The amount required to differentiate that sized white chalky substance on the surface from throughout that sized pot would be obscene...like...not possible levels.

Would water evaporating on the surface do this?Sips, so wicked up and evaporating at the surface? I get scaling on my taps also.

Still a ridiculous amount of calcite from hard water...think about how long it takes for that calcite to build up on faucets? Now look at that chunk in ur pot.. it dont add up.

I'm pretty sure it's saphrophytic fungus. It's caused by overwatering.

Earlier I posted this in a coco thread. I was using Blumats for the first real attempt and kept this poor plant too wet.

Yeah. Must be

Are you getting flakes like in my pic? I can’t quite see in your photo. Your appears fuzzy like mycelium??

 

[lusidghost]

It almost looks like perlite and is chalky when crushed. If you see it there's a good change your roots are suffering.

Edited title so not to confuse people with two different threads with same title. The new title is Not sure what this is.

Mine definitely is flakes. My pic is fairly clear when zooming in.

It's not Ca deposits.

 

[lusidghost]

I can almost guarantee it's the same thing. You really think calcium is crusting up on the surface? The soil looks pretty wet.
