Is This Powdery Mildew?

I've used the milk spray, the citric acid, the potassium silicate, h2o2. It kept coming back


Use Sulphur if it's in veg to kill it. Use arbor plant therapy for a preventative after you kill it with the Sulphur. The arbor has the same ingredients as Athena for 1/4 of the price.

Also how is your environment. What's your rh? Is your space clean, outside the tent too?

I'm nobodies expert on pests but that looks like thrips to me as well. In your first picture on the middle leaf on the left side of the midrib I think you'll see one of the offending bastards.

It's said that spinosad is safe to use but I hate to spray anything other than water on my plants.

I'm also surprised the other plants aren't also infested especially given the amount of damage to the one.

Good luck.

Safer insect killing soap works good too it's just potassium salts of fatty acids
