White mold on cloth pots

[roccus]

This started a couple weeks ago I took pics and asked about it on another forum and was told not to worry about it it is just salt or calcium.. we are having fairly high humidity here the past couple days I just switched to flower 2 days ago growing in coco using cana coco nutes in a 3 X 3 tent with 2 300 W lights I have 2 fans sitting on the floor of the tent blowing air around the pots and 1 fam on top blowing air at the top of the plants and a 6" exhaust fan sucking air out so I have a lot of air moving around in my tent, this is my first grow... when I peeked in on my plants today this is what I saw the mold had creeoed up the pots just about to the top, I do not see any on the plants yet..

Hey roccus have those pots been used before or is that the first time ??

I had the same problem but I didn't have mold mine was like salt or something but what I did was sprayed some PH water on it and it's cool but I do spray the pots every other day

It looks more like buildup to me, because I can see some of it sort of cracking off in this pic. If it's mold, it typically appears fuzzy or dusty like flour, but doesn't easily wipe off. Can you get a closeup of one of the spots?

Overall your plants look amazing

Hey Roccus, I may have said this in a different thread too. My cloth pots look exactly like yours and it's definitely salts / buildup from synthetic nutrients. In my case I knew it was salt because on one plant the white stuff gets bigger when I give it a nice feeding. You can actually watch the white stuff grow as the water goes through the medium. The water is flushing the salts out and they leach through the fabric a little.

Dude I don't know...........I've seen this before somewhere......can't remember where......but that brownish patch is where you have touched it?...right?....it sort of melts when you touch it!!.......I would scrape that stuff off dude.....even if I'm wrong, might be better to get rid of it anyway dude
