Wtf ? Yellow mushrooms growing in my coco

Wtf is this? I have 2 plants growing in a 2x3 scrog. Both plants are clones from the same mother and are about 3 weeks into flower. The plants receive the exact same nutrients fed to them through Blumat auto watering devices. The plants are growing in 5 gallons of coco/perlite. 1 of the plants has been growing slower and leaves have now begun yellowing. Today I see these yellow stalagmites growing under the blumats.

One thing to note, the coco/perlite is recycled from my last grow and wasn't really rinsed well (this problem was not present in the last grow).

Is this treatable, or should I just chop this plant and dispose of the coco? The plant on the right is the one with the problem - you can see how much better the plant on the left is growing.

Looks overwatered, the little yellow things are mushrooms... that is a really cool picture, I need to share it.

Whatever they are, they are killing that plant. I don't think the plant is over watered at all. These blumats work pretty good. Usually the plants grow roots up out of the coco where the blumats drip.

BGT,
Having grown mushrooms...I can tell you that underneath the surface, you have a shitload of mycelium growing. You could try and kill it, but whether you can keep the plant alive during treatment...well that's another question.

Remember that mushrooms release spores so don't let the muchrooms mature. Pull them asap. Better wash and disinfect coco in the future.

Thanks! How do I kill mycelium?

Daconil is an antifungal used to kill yard mushrooms. Something like that. Mycelium like lots of moisture so maybe run things a little dryer in that pot.

You could try a standard root rot treatment too.

Basically you're in uncharted territories! lol
Good luck,

I doubt the mushroom is hurting the plant...
My money is still on the medium being too wet.

bleach should knock the shit out of the fungus

Mushrooms removed.

But, can I dilute bleach down enough to kill the fungus, and not kill the plant?

try and just put some drops on it see what it does... fungi are pretty sensitive buggers,,

Those mushrooms are not harming the plant. Look elsewhere to fix the problem.

I've grown plenty of pot with mushrooms growing between the roots.

Maybe I have a root rot issue going on in this pot. Ill see what I can find locally to treat it. I shut off water/nutes to this plant and will let it dry out for a day or two to see if that helps anything.

To be honest it looks like it needs more water.

It's hard to over water in coco and perlite.

If anything those mushrooms were benefiting the plant (Look up Companion plants for a reference). As long as the spores aren't released its probably better, just remove what you can and don't worry, any toxins from a live mushroom won't make it up the stalk if your plant, the spore don't contain enough toxin to harm you, unless your snorting it......

Unless you using some kind of poisonous mushrooms as compost in your soil, I think you'll be just fine.

instead of having 2 blumat carrots per pot these drippers(up tp 5) can be attached in series to each blumat for an more even watering experience
