Hi, This is popped up in my tent on one plant, now it is on 2 to 3 leaves on 4 out of 6 plants. I'm fairly sure it is mould.
The reason is I bought a bag of compost and it had white mould in it. I was told all was okay and just to mix it back in as that is normal for some compost to get a form of mould but it is good fungi.

Two days after transplanting I noticed a white spot on one leaf, I gently cut it off and threw it away, the next morning, more, and now even more. It's obviously spreading. This is in my veg tent and I have my flowering tent next to it.

Can I get confirmation that this is mould, how to treat it organically, and could the soil is really been the cause of this? We have had a lot of humidity and I've been struggling to keep it down in the tent. PS. I dusted with cinnamon last night.
PS. I have had a a fungal gnat issue. I'm using fly paper and catch and average of 10-15 every few days.

Yep its a white powdery mold.

 

Keep humidity down and have sufficient airflow and it shouldn't happen.

 

Never had it myself but i found this link that might help.

I can second the Dr Greenthumbs products They are great I also use potassium bicarbonate as a preventative 

this one is eco friendly like the Dr greenthumbs stuff.

I've heard that works. Do you have to mix it with water, or just spray it directly onto leaves?
I have also found a spray of baking soda, dish liquid, and Was thinking that may help but if milk is a tried n true method I will go that road.

I found the green thumbs a tad out of my financial reach at the moment but I do appreciate your advice

Tried the baking soda first up, then the milk and water 60/40, slowed it down 

 

in the end I went straight milk, that worked great, stopped it from spreading completely

took a couple of sprays tho
