Mold in coco coir medium

pretty much sums it up already, woke up this morning and saw white mold in the bottom of one of my 4plants. Soil is already very dry i was about to water but wandering what i should do now.. The medium is coco coir mixed with perlite (about 30% perlite). Thanks in advance guys and girls,

Are you channeling Ray Charles with those photos? I can't see shit. Could you be seeing salt build-up? That can look similar to PM in my experience.

Why are you mixing coco with perlite? That's unnecessary and likely doing more harm than good.

Thanks for the quick awnser!
Its hard to take a picture of, maybe this one you can see better. Its white and a bit transparent looking.

I searched and saw many people saying mixing perlite with coco is fine but maybe your right

It may not produce negative results, but it won't produce more favorable results than straight coco will either. It's a soil-less medium, it does not need the aeration that perlite provides.

I still can't see a thing in that photo man, but from what I can tell, it's not salt build-up based on my experience with that.

I would go to wal- mart & get the garden- safe spray that works on mites, insects& fungus & spray the base of those plants I always kept an oscillating fan on my plants ,have a few coco grows under my belt I like 40% perlite/ 60% coco & smart pots good luck

I wouldn't spray anything unless you sure know it's PM, because I've never really heard of pm growing in your medium, what's your temps and humidity, I don't see any PM do you have a scope because you can tell if it is or not, it looks very fuzzy

I cabt get a clearer picture sorry guys.
I picked up the white stuff and threw it away. It hasent appeared back yet so i think ill just wait for now.
I alwais have a fan rotating on my plants. My temp is around 18-24C with humity between 35-45%
