Can anyone tell me what this white ashy looking stuff on my leaves are and if I should be concerned. My buds are developing fine. I'm a first time grower.
thanks
Phil

If you look close and it looks like indented silver tunnels it's pests. Thrips or mites.

Is it white and powdery or a bunch of tunnels of silvery material?

Wow. Don't be an ass.
There is a difference between seeing a 2D pic and seeing the real thing in front of you.
You can grab a leaf and rub your finger to see if it wipes off or not. We don't have that option.

Not being an ass. The pics is exactly what I see. Don't be so sensitve. Sounds like you need to burn one. I even used a magnifying glass and no it doesn't rub off.
Thanks.

Take a picture that has a high enough resolution to see the problem. White powdery mildew brushes off. The tracks created by the pests doesn't.

If it doesn't rub off it's pests. Thats what their excrement looks like. Powdery mildew is powdery. Sits on the leaf. Pest burrow into it and chew on it and leaves excrement behind.

Ok, I don't see any bugs unless they're microscopic.(tried a magnifying glass) Also the leaves don't look like they've been chewed on. Try to figure if I should treat for bugs or a fungus.
thanks.

Yes they will, some like to lay eggs under the leaves so predators won't see them as easily. White mold looks like cotton candy

Its definitely not cotton candy looking and I just went out and checked again in the brighter lighting and I saw some very tiny black spots and read its bug poop. I believe I did see some tiny bugs (only a couple) but too small to know for sure. Also do you know what a good spray to use. I don't want to smoke the buds that have insecticide that could be harmful. I bought some Fox Farm Don't Bug me. Heard good and bad reviews.
Thanks
PS Under all the leaves are clean, just on top has the white stuff.

If mold is ruled out,I would start by washing them all to get the most of them off then buy some insecticidal soap or something,maybe talk with someone who owns a nursery or bring a sample,those people deal with it for a living.

You won't see the bugs. You should treat for both bugs and fungus. 3 in 1 works. Because the bug excrement can cause fungus. Treat frequently.

I’d avoid spraying buds best you can.
