White Mold Please Help

[MoonDuneBuggy]

Hello everyone! On my last grow I had mold for the first time towards the end of flower. Now it seems i can't fight the mold even at veg for my current grow. Mold forms on the top part of the soil and the side of the fabric smart pots. I keep spraying with h2o2 but want to limit it since I am growing organic.

Humidity is at 53% temperature is at 78f.
I have a 250cfm inline fan running. With two ocilating fans inside the tent. The tent is a 2x2x6. I wait till the pot is light and then I water again.

I have a 2 pint dehumidifier in the grow tent. What are my options is there anything I can do about the spores.

The surface of the dirt honestly looks like beneficial mycelium.
The bottom isnt much of a great picture and it does look suspicious, if you let the run-off sit in the pot after watering then its possible thats also what you've got growing on the bottom.

Personally, id try to post a better pic of the bottom before further action.

Do not let bags sit in moisture. Elevate them off the ground. This looks like possible nute salt precipitate. On the bag. Get air moving under as well as over.

Thanks for the response. I never ever let it sit in runoff so that is not it. It was just transplanted so it's not salt build up either.

Its not salt build up since I literally just transplanted.

When I spray h202 it fizzes and dicintergrates away so I think that means it's cobwebs mold right?

If not salt you're not watering correctly .

H202 will kill good & bad fungi including good & bad critters, certain species of fungi are beneficial to cannabis, thats how they survive in the wild.

its important to have an accurate answer before dumping h202 down a fabric pot, a better pic would help because after all, it is a fabric pot & guess what white fabric looks like?

I've grown in fabric pots several times. I have never gotten what is on the sides before.

1. Figure out what it is.

2. Is it good or bad? If its good then let it be, If bad go to 3.

3. Take action to eliminate not just the problem but the source of the problem.


Here, some Issues for comparison.
