minionrebel559started grow question 4 years ago
I have a light white dust on my indoor Staples OG, it doesn't really come out in pictures well. When I look at it under the loop, it is crystal like but it's on the fan leaves. Does anyone have any ides what this might be?

Hard to see. Looks like a little powdery mildew. There are many possible treatments at this stage in veg. High PH (>8) foliar (like silica) will prevent PM spores from germinating, H2O2 is an option, wettable sulfur possibly. Prevention of PM is airflow and adequate RH. Looks like your RH is low already. Enough air movement? Good luck👍

White Spots on top of LeavesI have discovered white spots on my plants. I think it is white mildew. From what I have read, the spores cannot be killed. You can only stop them a with pesticides or, if you are lucky, with a milk/water mixture, but you cannot remove them completely. What should i do?

Help the HermyMy worst nightmare has become reality, my Pineapple Chunck (Week 7 of Flower) has developed male pollen sacs. What is your advice for me now? Remove the whole plant? Cut off branches? Harvest the plant now? The other plants are showing no signs, but I'm afraid it will be seedy 😵

Is this powdery mildew? How can we know for sure?Could these white spots be mildew? We could easily just basically shake them off, without any residue remaining. Currently only discovered in those two spots seen on the picture.
In pics I find from mildew, it usually starts more dusty.. I also made one picture under the micro.

What are your best experiences for treating white powdery mildew? (4th week of flower)I carefully removed all the leaves with WM on it, but i want to spray the leaves to hinder further development of the mildew. What are your best experiences? I've read about milk solution, maybe citric acid solution with a ph of 9? Can i spray the buds too? Thanks for your help!

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%.

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.
