    Is this PM or?

    Looks similar to a powdered detergent with a bit of water added to make a paste. but after looking at it under a scope, it's a webbing or fiber like material. The last pic is best viewed from a phone so you can zoom in to see the detail. I've looked over all of the plants, and it seems that this is the only branch or leaf that had anything on it.

    PM has a lattice structure that starts in small spots that become larger until the entire surface is covered. I don't see PM on stems very often. It would start on the leaf then grow onto the stems. Yours looks more like spider webbing on the stem part?.. The leaf looks more like PM. Always treat it as if you do have PM. When caught early it's not hard to get rid of. Always have an organic treatment on hand for such things,

      It looks like what's left over from mealy bug presence, powdery mildew looks like a hazy white dust. If you notice it again run your finger down the affected area and see if a Mealy bug jumps off onto another stem. Neem oil will take care of them

          I poked around at it a bit, and nothing moved, and when I scoped it there were no bugs that I could see. Come to think of it after Hammerheads reply though, I have been seeing spiders at least once or twice a week on a plant here and there lately, but I've never seen a spider that would make a web around an object, but rather between objects.

          The Mealybug assessment would make sense however, as I was able to easily rub it off, and it came off in cotton like pieces, and I have been loosing random leaves over the past few weeks. The stem of the leaves will just start to wilt away about halfway up, and the leaf will drop. I haven't been able to spot any bugs however. I've also caught a few spots on the tops of a couple leaves that are wet when there's no rain or dew.

          I'll up load pics of the leaf damage in a moment.

              If 1 leaf has it all have it. Spores are everywhere in our gardens.. I would treat the plants and area with an oil based organic spray. I use GrowSafe Bio-Pesticide as part of my IPM. This is a Corn/soybean oil treatment. It will keep pests and molds under control.

                I gave them a good spraying with this. I've used it indoors before when I had a gnat problem with an rdwc grow.

                  If possible immediately isolate infested plants from others to prevent the mealybugs from moving amongst them. 😎

                        Unfortunately no way to separate. They're in ground, and I've noticed the leaf issue on at least half of them. Hopefully the Fungicide 3 does the trick, and I don't have an issue when they start to flower in about a month. I need to get started on building framing for a plastic roof to help protect from bud rot late in flowering. I'm not sure how long this strain is going to flower for, and we tend to get rain around the last week or two of October.

                          Hey Chuey look up a Flatid planthopper they leave some powdery stuff behind too. Im sure the fungi spray will do the trick. Even blasting them with pressurized water every once in a while can help. I dont think its mold. Plant some flowers around them and get the Beneficial's in there, I use marigolds and the bees/wasps carry them things away.. Wish the best

                            I didn't know you were outdoors. You have had a moisture issue and some point in your environment, and was too wet for too long. To dry things out, you need to aerate the soil and keep it loose, and turned, to allow the roots to dry out well, between watering's. IF you are getting, or in a lot of rain, then you can block the rain, with hay mulch, and keep the rain from hitting the ground around the plants. . When the rain leaves, remove the wet mulch from around the plants to dry for later use. 😎

                              I have never seen any good results using fungicides on any kind of fungus, indoors, or outdoors. Once the fungus is alive and disperses spores in the environment, they will always be there until the right conditions and bloom again. I've seen a lot of money wasted using fungicides and get hardly any results. When the conditions are just right for a fungus bloom it can be only 3 to 12 days a year. People buy fungicide and spray their plants and then the weather conditions change and get better, and they think the fungicide fixed it. Unfortunately, people buy a lot of fungicides, and spray it on everything, every year, and think the fungicides or NO good. They don't work! I don't put FUNGICIDES on anything I eat, of vape, and don't recommend it to anyone. 😎
