Washed some fresh coco, is this salts or pearlite?

[Siz]

Was reading over 1.0 EC runoff

Got these deposits

Mother earths coco pearlite 70/30
Floraflex loose fill

I should add I used RO water 0.0 EC

It looks like a salt residue of sorts, but I've never run coco

 

[Bilber]

I'm agreeing with canna....

 

[crimsonecho]

looks like perlite dust as the company claims medium itself is just coco and perlite without any additives.

ps: i never washed coco even the dry bricks from good companies. using it in my organic no tills after just rehydrating without problems.

Anyone with coco experience?


I dont think pearlite would raise ec and I dont think its from the mother earth as I havent experienced this before.

The hydro store didnt have any more mother earth 70/30 coco mix so i mixed the last bag i had with a bag of floraflex loose fill 52.5% whc
