White spots on leaves
RollinRick
started grow question 5y ago
There are some white spots appearing on my leaves on a couple plants in the same tent? All are at varying stages of life, but one - which has not flowered (probably a photoperiod) doesn't have the same.

Looks like spider mite infestation. I use microbes to kill pest. My favorite for spider mite is Beauvaria bassiana.

White misty layer on my leaves
Noticed the last days some light white covering on my leaves, if I go over it with my finger it disappears. Branches look good and green, no brown places on the branches, nothing wrong with the buds, they développe great. They are now in their last week. It's only on the leaves.

I've had issues with PM in the past. Safers brand 3 in 1 seems to work temporarily but it always comes back. Also seems like it may deteriorate the trichomes on a flowering plant. RH 50% I currently am using a worm casting foliar spray and all is staying well. Any more tips?

White Powder on Leaf
Here's a closer shot of the white powdery stuff, only on one leaf right now. I'm going to keep an eye on it and try not to worry for now. If I suspect it's mildew, mold, or Fungus I will take action. What does it look like it could be to you all?

Welcher Mangel ist das?
Seit etwa 10 Tagen zeichnet sich ab, dass meine Blätter braune Flecken bekommen. Diese werden leider immer mehr und größer. Kann ich jetzt noch aktiv gegensteuern? Des Weiteren erkenne ich kleine weiße Punkte auf der blattoberfläche. Sind das Salze?

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?

I have noticed small powdery mildew spots on my pineapple express plant. The soil usually feels pretty dry so i don't think it is due to overwatering. I put them inside at night due to humidity outside. Should I separate this plant from the rest?

Difficulty identifying leaf problem - maybe it's insects?
I'm having trouble figuring out what's going on with my plant. The cotyledons and lower fan leaves are getting irregular shiny patches varying in size underneath, with yellow spots directly above them on the top side. It's really hard to photograph the shiny patches. Thrips?

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.

White powdery mildew in late flower
What's your best remedy to remove it on flowering plants? I just found it after I had forgotten to replace on of the fans when I left them for a few days. What can I do to remove it as quickly as possible without ruining the buds? I'd prefer not spraying them with milk.

I'm starting to see some white spots on one of my plants and the bottom leaves are stating to yellow is it just fungus or potentially thrips? My other plant beside it doesn't seem to have to have the same white spots on it so I'm not sure if its spreadable.

WPM
I found WPM on a few leaves. I was spraying spinosad at night. I stupidly thought spinosad would take care of that to. LED light showed much more PM but early stage. In A.M. sprayed 1tbsp baking soda, soap, veg oil per gal. Used 2 gallons. Will any of this interact? Thanks
