Is a plant mushroom in the rectangle on the leaf?...
BowlBroanswered grow question 4 years ago
Looks like powdery mildew. A group of fungi that get on a lot of houseplants and vegetables like squash.
You can try one tablespoon baking soda and one-half teaspoon of liquid, non-detergent soap with one gallon of water, and spray the mixture liberally on the plants morning and evening.

It’s either powdery or evidence of thrips. Most Likely to be powdery mildew. The formula that bowl brow suggested works, and I’d also add one half teaspoon of hydrogen peroxide as well to ensure all the bad bacteria on the plant is being killed off

Is this powdery mildew?I just noticed this tiny white spot on a leaf of two different plants and having trouble ID’ing it. It doesn’t seem powdery or fuzzy and almost looks like a mineral deposit… but I really have no clue.
Appreciate any ideas—thanks!

how many times should we spray with milky water in case of powdery mildew when we are in bloom? do you have to spray with this solution every day?Several people here advised me to dilute the milk spray with water, I did it, I diluted 400 ml of milk with 1200 ml of water, then I sprayed the plants in the tent, since they are grown in scrog, it is difficult to get everywhere.

Powdery mildew or just... chalk?Can someone confirm if this is powdery mildew or just chalk from misting, please? The walls of the grow tent had a little chalk on them too so that's why I am not a 100% sure. Temperatures have been quite optimal for late flower and humidity has not even been over 40%.
