White Mold on Stem

I have a plant with what appears to be a type of mold on the stem. What ever it is, it looks like some form of polyps or little mounds of powder. I know it is some sort of mold or fungus because my experiment involving on plant cloning via wrapping stems with wet medium made them grow like crazy.

Anybody know what this is?

Have any pictures?

My first guess is powdery mildew. Try high ph water on it but if it is there it is going to be a battle if not treated right away. Sulpher burner is the best or else there are organic sprays some home remedy is milk water at 30% skim milk.The stuff has cycles 1-7 days so a weekly treatment of one of the above until you don't see any more.Hitman40

is it like a hole bunch of little white bumps. on just the main stem lower, closest to the soil.?? if so it could be just roots that want to come out. mine do it all the time so i just pile up more soil around it and out comes the roots. its from not planting them as far as they could have bueen but cant say for sure with out pics.

That is exactely what it looks like and I used to think they were undiferentiated cells turning into roots. But, this stem is infested heavily and I wrapped the stem with wet paper towel as a rooting experiment and they grew into large white clumps.

Powdery mildew sounds like the most likely culprit. No biggie though, this plant is looking like a lost cause. I'm just hoping the cuttings I took from her do well.

I'd also like to understand this stuff. How does one prevent it, is it always present and when does it become an issue?

This is what I suspect as well. Judging by what you've told us it doesnt sound like mold. I would try spraying it with a neem oil solution, coulnd't hurt.

I have 4 plants growing in hydro dwc just now. They all started out well and filled out nicely until a couple of weeks ago. One plant is still growing very quickly but the other 3 began to become sunted. The plants began to have a tremendous growth of bud nodes low on the stalk and limbs and well below the canopy. Just as quickly as all these brushy nodes started growing all the fan leaves below the canopy startrd dying. I couldn't come up with any sign of anything that might be causing the problem. There had been a certain amount of brown spotting on leaves of all the plant from the moment I transferred them them into hydro using hydroton alone as the growth medium.

Anyway this kept me stumped until today. When I began pulling the plants and clearing away the dead/dying foliage. That's when I found the pictured fungus below the surface of the hydroton medium.

Can anyone name that tune? I started working on the crud by lightly spritzing the stem and foliage with 3% H2O2 and spraying the top of the medium, into the sides of the netty pot and the root system with the hyrogen peroxide and allowing the root system to sit in the solution for a few minutes.

What else might be in order to finishing killing the crud out?

Many thanks. Enjoy life's little pleasures... A good joke and a good toke are great!
