which bugs leaves oily residue on leaves?

[Marshall]

I have this bug problem that I thought was spider mites. But I am thinking it may not be. The top of the leaves get these white flakes on them that will blow off easily, and the top gets this oily film. The underside of the leave has bugs that look like spider mites, they are orange and pretty small. But there is no webbing, and the problem doesnt transfer to other plants untill a neighboring plant grows into it and touches it.

Never heard of a bug that leaves an oily residue

Had fungus gnats but that seems to be resolved through mosquito dunks and sticky paper. Nothing flying around.

Been using Azamax and floramite. Today used some Avid

Aphids, they leave a sweet sticky exude as they feed. Ants love the stuff they actually will hold aphids captive and make them produce the sticky sweet exude for them by using natural pheremones to control them! It's some serious mind control bug chemical warfare out there!

Spray em off with a natural soapy water (Dr Bronner's Castille soap from health food store get the lavender or peppermint one) & lavender essential oil mixture. 2 teaspoons of the soap in a gallon of clean water, add 25 drops of lavender essential oil and shake well. Spray down everything under and over, soil, pots, and try to do it in low light so nothing burns. The soap & oil is harmless to plants.

thrips leave a "silvery" trail

spinosad if thats the case

Are there any dark spots - insect feces on the leaves? Do these bugs run away quickly if you try to squish them or is it an easy slaughter?

You may have multiple pests. Sounds to me like both mites and thrips.
The mites won't web up until a full on infestation has taken place, leave them alone till flower and you'll find webs.

When treating with anything, you must continue the treatment and repeat...especially with mites. They may meet their demise from a treatment, but their eggs may well make it and hatch later. I think most mites are on like a 3 day cycle, in that when they are born they are ready to lay eggs, and this cycle repeats every 3 days.

I also agree with the spinosad treatment. It seems to take care of both mites and thrips. I will use it in late flower if there is a problem.

i am thinking 2 different bugs.

One looks like a spider mite, the other looks like a fungus gnat but they dont fly. Just looked in the infirmary and it says thrips look like gnats but dont fly.

There is not much damage to the leaves, will look closer today. The plant that is severely affected was harvested and is being revegged, so the leaves are a little deficient due to pre-harvest flush. curerently on 18/6 and moderate nutrients.

I did wash the plant off with warm water.

There was white stuff along with oily residue on the top of the leaves, and black specks, mite looking bugs, and gnat/thrips on the underside.

I will try to take some pics of anything that may be left but the camera may not show that close detail

Keep treating them and the plants around them until well after you think the problem is long gone. It won't be gone, and if you neglect for even a short period of time, it will be back in full force. Good luck!

Here are some pictures. Was able to get a pretty good shot of a bug. You can see all the white stuff on the leaves. This is after spraying with Avid and getting rinsed off. Obviously I missed some spots

aphids and scale bugs both leave a residue on leaves.
