Is this powdery mildew?

This is my third grow and some faint white spots started to appear on the leaves of my young gelato 41 plant. Is this powdery mildew? If so, what is the best way of treating? I can't clip the leaves yet because the clones have only been rooted for about a week and it's on almost all of the leaves.


So far to treat it:

I lowered the humidity in the tent to 60%

Treated with a foliar spray of 1ml/1cup hydrogen peroxide.

Any other recommendations?

No! It's not PM. PM is dusty as its name suggests. It looks more like bleached-out spots from water droplets on the leaves magnifying intense light, but it could be some TE deficiency.

Citric acid or a commercial product like NukeEm will take care of them. You'll want to follow up with a preventative and start an IPM regimen.

I ordered some azamax that should be here tomorrow.

Today, I ended up treating it today with a foliar spray made up of a cup of water mixed with 30ml rubbing alcohol and a drop of dish soap.

I also added hella fans to my tent for airflow. Hopefully the azamax will kill them over the next week or so (hopefully sooner), then I will pull everything out of the tent and sterilize with bleach.

I'm always open to recommendations if anybody has any. I always appreciate the help from everybody in this community.
