Hi, we can see a lot of little white spots on the big leaves. Have you checked underneath to see if there's a mite infestation? (A microscope can help)

Is this powdery mildew?
Is this powdery mildew? I am seeing some white spots starting to form on the underside and top side of lower fan leaves. Would adding an oscillating fan help prevent anymore white spots from appearing in the future or will I need to apply neem oil or something?

Spider mites?
My partner just cut some clones off of a pre-flowering plant & put them in a root rain spray cloned. Been 2 days since he cut the clones. No roots yet but he’s wondering if he has spider mites & if so what he should do. Do you all notice anything wrong?

Help the Hermy
My 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 😵

Too little light
I have now tried removing the WPM by smiering 40/60 milk/water on the affected areas. Deep inside the canopy aswell since little to no airflow passes here due to the plant being so deep in the pot. And apart from that the plant recieves 8 hours of light and I cant install a LED.

Is this powdery mildew?
Could this be powdery mildew on the pictures? I have to add that the spots were a little more fluffy but I removed some of it with my finger. The weather has been really dry, so I thought it was impossible, but it still looks like it. If it is powdery mildew, what should I do?

Bagnare foglie
Hey everyone. Yesterday I sprayed neem oil and there are some drops left on the leaves leaving a white powder. Can I spray just water on the leaves with the lights on (24-hour cycle) to try to wash away these residues, or will I burn the leaves by wetting them? Thanks a lot!

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? 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.

Mildiu polvoriento, sugerencias de como seguir?
I have 4 autos 1 week away from harvest, I have a slight powdery mildew, I’ve cut the affected leaves and sprayed with 1 part milk and 9 parts water. I'm sure some leaves must still have mildew, but I sprayed everything pretty well! I've only done it once, how should I proceed?

Minor damage to a few leaves found today - what is it?
I am trying to determine the cause of damage to a few leaves that was observed this week. It may be two different problems. On a few leaves, I see brown spots which may have originally been white. On another 2 leaves, I see a burn hole through the leaves with brown edges.
